Video Transcript for Curt Accessories and Parts D-192 Review

Today we're going to be reviewing part number D-192. This is the Curt Dual 2" Receiver Tube Adapter, providing an 8" Extension. The top receiver opening is not for your towing use. This is where you would install your hitch mount accessories such as a hitch bike rack. The bottom receiver is for towbar or trailer use. For instance, you could hook this on to your RV, flat tow your vehicle using the bottom receiver and carry at hitch carrier bike rack using the top receiver tube. It is going to come with a 5/8" pin and a clip.

That's to secure the inside of your trailer hitch. The gross trailer weight of this unit is going to be 3,500 lbs with a maximum ton weight of 350 lbs. if we take a measurement from the center of the hitch pin hole to the pin hole on the receiver tube. That's where we're going to get our extension measurement from right at 8". The distance that we have from the center of the hitch pin hole to the back of the receiver tube, that's going to give us a measurement of 5". Then 5 1/2" from the center of the hitch pinhole to the back of the center support bar here that connects to the receiver tube portion.

If we take a measurement from the inside top edge of the bottom receiver tube to the inside bottom edge of the top receiver tube. That's going to give us a measurement of 3 3/4". Please keep in mind that using a hitch extender will reduce your hitch's overall capacity by 50%. It's made from a solid steel construction. It has a nice finish on it so it is going to stand up really well against rust and corrosion. It's also a really simple installation.

All you have to do is slide the shank into the receiver tube of the hitch. Line up your pinholes. Then you can insert your hitch pin and clip or hitch pin and lock to secure it inside of your hitch. That's going to do it for today's review of part number D-192. This is the Curt Dual 2" Receiver Tube Adapter, providing an 8" Extension. .

by: Tim Fannin08/06/2012

I ordered this product to be able to tow a car and haul 4 bikes on a bike rack. I used it first on a camping trip 150 miles away. The product works as advertised. I towed a Pontiac Grand Am and caried 4 heavy mountain bikes with no problem. I did have to get longer chains and an extension for the electrical hookup for the tow dolly (the extender adds about 8 inches). I was initially worried about clearence between the bike rack and the car but that turned out not to be a problem at all and could have addded a fifth bike easily. I probably had 150 pounds of bikes plus about 100 to 125 pounds of tounge weight from the Grand Am on a tow dolly. This is close, but still under the limit of the product and had no issues while driving across some very bumpy roads. It was worth every penny not to have to drive a motor home and car seperately. It will certainly pay for itself on longer trips. 50764

Exactly what I needed for my motor home. I'm able to carry a receiver hitch bike rack with bikes and still tow my car. Works extremely well. This dual receiver is built very well. One point. For my needs, I also purchased anti-rattle locking bolts to take the "play" out of the hitch connections to stabilize the bike rack. They perform exactly as advertised. The bikes are very stable on the hitch except where the dual receiver mounts to the original receiver. Since the dual receiver is built so well, the "male" end is solid steel and not hollow. Therefore, internal locking bolts cannot be used. An external anti-rattle device is required at this connection and they are harder to find. 31248

Product did what it is supposed to. I would have liked the product to have been able to have a higher weight tolerance. Also, the designers need to look into making a product with a higher second mount. If a trailer is towed, the second mount needs to be much higher to have clearance for bikes, etc. 212307

Hitch receiver very well built solid steel shank so the anti rattle hitch pin could not be used on it. I put it on the back of my motor home so I can use the bike rack and tow my Jeep at the same time. Drlrvery time through UPS was outstanding as we move quite often because we full time RV. 173466

Overall, this is exactly what I needed. The only reason that it's not Excellent is because the weld seam between the front and read of the hitch is approximately 1/2". This causes the receiver not to line up with the hitch receiver unless you're able to "lengthen" receiver holes. 159603

Great service! I received the adapter in short order and in great condition. I have a need to tow a car and a double trike carrier with my RV. Before I purchased this adapter I had a choice of towing one or the other. Now I can take both! 9967

The dual hitch is great and fits well into our RV base and will allow us to tow our Mini Cooper and also attach a bike rack for our two bikes. Felt the price was fair and a solid product. 165919

Ask the Experts about this Curt Accessories and Parts
Do you have a question about this Accessories and Part?

  • Can Trailer Hitch Mount Bike Rack and Cargo Carrier be Used at Same Time on 2013 Hyundai Santa Fe
  • It looks like you purchased Curt trailer hitch # C13153. With any of the trailer hitch mount cargo carriers that we carry you cannot insert a bike rack in the square tube that runs down the middle of the carrier. There is no pin hole and the extension of that set up would be too much torque even for a Class III trailer hitch. You could use dual receiver adapter # D-192. You would put the bike rack in the top and the cargo carrier in the bottom. However, the bikes will hang down over...

  • Can a Trailer Hitch Mount Bike Rack and Cargo Carrier be Used at the Same Time
  • With the 24x60 Railed Cargo Carrier, # 63153, installed in the trailer hitch, you will not be able to install anything else in the hitch and nothing can be installed in the tubing in the cargo carrier. What you could do is use the Curt Dual 2 Inch Receiver Tube Adapter, # D-192. However, the bikes will be hanging above the cargo carrier, limiting the amount of space on the carrier. Also this adapter/extension has a tongue weight rating of 350 pounds. This means that the cargo carrier,...

  • Best Options for Carrying a Hitch Mounted Bike Rack and Towing a Trailer
  • The # D-192 that you referenced will cut the capacity of the hitch it is installed on in half so I would instead recommend the # D210 which does not have the same capacity reduction and would provide you with a ball mount plus a second hitch opening for carrying a bike rack. Since you have an A-frame trailer a better option might be the Stromberg Carlson Bike Bunk Trailer # CC-275 that will install on the frame rails of the trailer. The capacity of this is 100 lbs though so you would...

  • Using a Dual Hitch Adapter to Carry a Bike Rack and a Cargo Carrier
  • Due to the lower tongue weight capacities of trailer hitches that have 1-1/4 inch receivers, there are no dual hitch adapters available for a 1-1/4 inch trailer hitch receivers. The adapters are only available for 2 inch trailer hitch receivers. If you have a 2 inch trailer hitch and a bike rack or cargo carrier with a 1-1/4 inch shank, you could use a hitch reducer like part # HT02 to allow you to use your hitch mounted accessory with the dual hitch adapter. Please note, the dual hitch...

  • Dual Reciever Extensions for Flat Towing a Car and Using a Cargo Carrier
  • Yes we do have an adapter available that should work for you. You could use the Curt Dual 2 Inch Receiver and Extension, part # D-192. You could also use one of the Roadmaster versions, part # RM-077-4 or RM-077-2. These parts are only to be used with a rolling load such as a vehicle being towed with a tow bar and should never be used to tow a trailer.

  • Dual Hitch Adapter with a Capacity Greater than 5,000 lbs
  • Check out the Roadmaster Dual Hitch Receiver Adapter # RM-077-4. This product is very similar to the Curt Dual Receiver Adapter # D-192 you referenced except it has a 10,000 lb capacity. This item is for towbar use only.

  • How to Carry a Trailer Hitch Mounted Cargo Carrier and Bike Rack Together at the Back of an RV
  • What you can do in order to carry both a bike rack and a cargo carrier is to use Curt Dual Receiver, # D-192. This receiver fits in a 2 inch trailer hitch and has two 2 inch receivers. It has a tongue weight capacity of 350 pounds. The bike rack, bikes, cargo carrier and contents all will count against the tongue weight. You will also want to make sure you are using a bike rack that is rated for use behind a motor home or trailer. I have included a link to all of the bike racks that...

  • Can I Use Curt 2-Inch Dual Receiver Adapter # D-192 as an Extender for a Bike Rack
  • Since the rise/drop hitch opening of the Curt Dual 2 inch Receiver Tube Adapter # D-192 is designed to be used with hitch accessories such as a bike rack I believe the # D-192 would be the better choice to give you a little extension and drop so you can clear the spare tire and open the rear area with the rack tilted. A couple things I would like to point out is when you use a hitch extension you cut the capacities of the hitch in half due to the increased leverage. Also, you will lose...

  • Can Curt Dual 2 inch Receiver Tube Adapter, # D-192 Be Used With Weight Distribution
  • The Curt Dual 2 inch Receiver Tube Adapter, # D-192, can be used to tow a trailer with the bottom receiver while carrying a bike rack in the top receiver. However, you will not be able to use it with weight distribution. There is another option. Since you have a pop up camper you could use the Pop Up Camper Roof Mount 4 Bike Rack - Swagman Pop-Up Mighty Rack # S80550. You install this rack right on top of your pop up camper. You will not have to worry about the tongue weight or adding...

  • Hitch Adapter Needed with a 6 Inch Extension and a 2 Inch rise
  • The Roadmaster Dual Hitch Adapter, part # RM-077-2, may be what you are looking for. It is designed for tow bar use only and is not to be used with any type of trailer. This adapter fits a 2 inch receiver and will give a 2 inch rise and drop. The overall length of the hitch adapter is 14-3/4 inches and the measurement from hitch pin hole to hitch pin hole is 6-3/4 inches, which is the amount of useable extension when installed in the receiver. You may also be interested in the...

  • How to Use a Cargo Carrier and Bike Rack Together
  • Depending on your rack and carrier, they maybe able to be used at the same time, but more than likely, one will interfere with the other. Keep in mind the shape of your bike rack may interfere with loading cargo on your carrier and the carrier may be in the way of the bikes hanging down. If the cargo carrier has sides or rails that are tall, they may prevent the bike rack from being installed. Additionally this adapter/extension has a tongue weight rating of 350 pounds. This means that...

  • Can Curt Dual Receiver Adapter # D-192 Be Used to Tow and Support a Cargo Carrier on 2011 Jeep
  • Use of any hitch adapter or extender, such as the Curt Dual 2-Inch Receiver Tube Adapter, part # D-192, will reduce your hitch capacity by 50 percent. This reduction in hitch weight capacity occurs as a result of the change in the geometry of how the weight load is applied to the hitch. In the case of your 2011 Jeep Wrangler all of the 2-inch hitch receivers we offer all have a 350-lb tongue weight rating; with this cut in half by use of an adapter/extender, you would have only 175-lb...

  • Raised Receiver Needed to Raise a Thule Bike Rack To Safely Carry Bikes
  • Yes, we do have a solution for your Thule hitch mounted bike rack. We have 3 different parts you could use to raise your bike rack to safely carry your bikes. The Curt Dual 2 Inch Receiver, item # D-192, or the Curt Multipurpose Ball Mount with 2" Receiver for Bike Racks and Cargo Carriers, # D210, would both be good choices, depending on the style you like.

  • Dual Hitch Recommendation for Carrying a Thule Apex Bike Rack and Towing a Small Trailer
  • The Curt Dual Reciever Hitch # D-192 that you referenced should work well for you as long as the hitch on your vehicle has the capacity for the tongue weight of your trailer plus the weight of your Thule Apex Swing Away Carrier # TH9027 and bikes. You should note that when you use a hitch extender such as the # D-192 you cut the capacity of the hitch in half. So as long as you confirm that you have enough capacity you should have no problem using this setup. I attached an FAQ article...

  • Can I Use Curt Dual 2 Inch Receiver Tube Adapter Part # D-192 To Tow 9K Trailer and Carry Bike Rack
  • The item you selected, Curt Dual 2 Inch Receiver Tube Adapter, 8 Inch Extension, part # D-192, is only rated for a GTW of 3,500 pounds and a tongue weight of only 350 pounds, which your trailer surpasses significantly. To use part # D-192, you would have to stay within the total tongue weight capacity of 350 pounds, when using both 2 inch receiver openings. So for example, if you had a trailer with a tongue weight of 200 pounds attached, you could only use a bike rack and bikes with...

  • I recommend using the Darby Extend-A-Truck Hitch Mounted Load Extender and Single-Bar Roof Rack # DTA944-968-924. The Extend-A-Truck load extender includes a single roof rack bar and is an economically priced load-carrying alternative that fits multiple cargo applications including your portable, fold-up boat. You will also need a pin and clip like # PC3. I have included a video review of the load extender for you to check out. If you intend to tow your bumper pull camper too you...

  • Hitch Adapter to Raise Cargo Carrier by 3-4 Inches
  • What you're describing is called a high-low adapter. They work very well keeping the tow bar level when you're flat towing a vehicle, but they're not designed for elevating a hitch mounted accessory. The Roadmaster # RM-077-4 dual hitch receiver offers just the rise you're looking for, at 10-1/4 inches from pin hole to pin hole, it's slightly longer that you wanted, but it should work just fine for you. Another alternative, the Curt # D-192 offers a bit more rise, but is shorter at...

I suggest you check your RV owner's manual for any guidance or restrictions regarding the use of bumper- or frame-mount hitches and accessories. For safety and capacity I suggest a frame-mount hitch for your...

  • Ball Mount Recommendation to Carry a Cargo Carrier and Tow a Trailer at the Same Time
  • We do have an option for you that would work better than the Curt Dual Receiver, # D-192. I recommend the Curt Multipurpose Ball Mount, # D210. This ball mount was designed for your application; towing a trailer and carrying an accessory at the same time. It has a higher tongue weight capacity as well. The cargo carrier and cargo loaded on it, plus the tongue weight of the trailer all count against the 750 pound tongue weight capacity of this ball mount and the receiver portion of the...

  • Can a Dual Purpose Ball Mount be Used to Carry a Dirt Bike and Tow a Seadoo Trailer
  • I spoke with my contact at Curt and he stated that the dual purpose receivers and ball mounts are not rated for use with something like a dirt bike and carrier. The issue is not the weight but where that weight is placed. It will be too far from the receiver and can cause it to fail. The best option, but still not ideal, is to install a front mount hitch, # 33328, and use the dirt bike carrier in it. However, my contact at Curt did state that for every foot of distance the weight is...

  • Solutions for Towing Pop-Up and Carrying Bikes Simultaneously
  • Using a ball mount in the Curt Dual Receiver Adapter will place quite a bit of downward leverage on your receiver. You will then have three connection points between the receiver and the trailer coupler, which will add a considerable amount of bouncing, which is why I would not recommend using it for this purpose. A much better option would be the Curt Multipurpose Ball Mount, part # D210. The ball mount can handle 750 lbs of tongue weight, with the receiver portion having a capacity...

  • Adapter for 1-1/4 Inch Hitch to 2 Inch Receiver with Rise for a 2006 Acura TSX and Bike Rack
  • When we installed Hidden Hitch trailer hitch # 60831 on a 2006 Acura TSX it measured 4 inches from the center of the hitch pin hole to clear the rear bumper. The Curt adapter # D-192 will not fit because it only fits in 2 inch trailer hitch receiver openings. And the MaxxTow one, # MT70355, will not fit since it is for Class II hitches. That leaves Brophy adapter # HT5R. It will fit a Class I hitch but the issue with it is that the back of the 2 inch receiver does not come out far enough...

  • Using # D-192 Dual Hitch Receiver to Carry Bike Rack and Tow Trailer with 2011 Mazda CX7
  • The Curt # D-192 might be an option for you, but I am afraid once you place a ballmount in the rise orientation in the bottom receiver opening, there will not be enough room to install your bike rack. Your best option would probably be a trunk mounted rack like the Thule Raceway, which is available in a 2 bike (# TH9001PRO) or 3 bike (# TH9002PRO) capacity. If you went with a trunk mounted rack, I would recommend using an extra-long ball mount like part # 4285 to provide extra clearance...

  • Can I Use the Curt Dual Receiver to Tow a 16 Foot Aluminum Fishing Boat and a Bike Rack
  • The Curt Dual 2 Inch Receiver, item # D-192, can be used to tow a trailer and carry a bike rack or cargo carrier. The top receiver is not to be used for towing, so your ball mount must be placed in the lower receiver for towing the boat. You then need to consider the capacity of the lowest rated item in your system. The tongue weight capacity for the # D-192 is 350 pounds and the towing capacity is 3500 pounds. Check the towing weight ratings on your hitch and vehicle to be sure they...

  • Using Dual Receiver Adapter # RM-077-4 For a Winch Mount and Towing a Car Hauler
  • Per its manufacturer, Roadmaster, the Dual Hitch Adapter you referenced, part # RM-077-4 cannot be used for towing a trailer. It is designed for a rolling load only. Curt makes a dual receiver adapter, part # D-192 that might work for you, but using any adapter or extender will lower the tongue weight capacity of your hitch by 50 percent. Also, a trailer hitch is designed to withstand horizontal pulling forces or tongue weight suspended from it, but a pulling force coming from an upward...

  • Recommendation For Mounting Spare Tire Carrier On 2014 Dodge Grand Caravan
  • We do not offer a front-mount hitch designed to fit your 2014 Dodge Grand Caravan. In my research I was unable to find any hitches designed for the front of your vehicle. Mounting a spare tire to the front of any vehicle runs the risk of blocking the air flow to the radiator and causing the vehicle to overheat. That can prove to be costly which everyone wants to avoid. My best recommendation is to use a rear trailer hitch with a spare wheel attachment. I recommend the Curt Trailer Hitch,...

  • Is the Curt Dual Hitch Receiver # D-196 Open in the Back for a Long Shank Bike Rack
  • The top receiver on the Curt Dual Receiver, # D-192, is actually open in the back so the length of the shank on your bike rack will not be an issue. Using this device you will get about 3-1/4 inches more height from the top of the receiver opening on the trailer hitch. The tongue weight capacity of this item is 350 pounds. However, the use of this adapter reduces the tongue weight capacity of the hitch by 50 percent. The combined weight of the bike rack and bikes cannot exceed the reduced...

  • Adapter Recommendation for Lowering a Yakima Doubledown Bike Rack

Check out the Curt Hitch Adapter # D-192. You could flip this product so that the additional hitch opening sits lower. You should note that any time you use a hitch extender or adapter you cut the hitch capacity in half. So you will need to determine if half of your hitch capacity will be enough for the weight of your bikes...

  • Can I Use Curt 2-Inch Dual Receiver Adapter # D-192 to Tow a 2006 Honda CR-V and Carry Two Bikes

So you would be fine to tow your vehicle if you do not load up the CR-V with more than 200 lbs of cargo. To use part # D-192, you would have to stay within the total tongue weight capacity of 350 pounds, when using both 2-inch receiver openings. The tongue weight will be minimal...

A dual hitch adapter, like part # MT70070 might be a good alternative. This adapter provides about a 6 inch rise, or Curt offers the # D-192 that also might be a good choice. Keep in mind, using either of these adapters will reduce the tongue weight capacity (maximum amount of weight that can be suspended from hitch) by half. For instance, say you're wanting...
