Video Transcript for Curt Hitch Locks - Standard Pin Lock - C23556 Review

Today we're going to be taking a look at part number C23556. This is the Curt Lock Set for the Adjustable Channel-Style Curt mounts. It is for use with the Curt channel-style adjustable ballmounts part number C45900, and part number C45901. The use of these pins retain the full capacity of both of those ballmounts when used. The lock is going to measure with the pin from end to end of 6 1/4 of an inch. You can see there that's the same measurement for both sets here.

This one right here is going to be the one that secures your ballmount to the receiver tube of your hitch, and then this one right here is going to secure the ball platform to that actual mount. Now the inside width measurements of each one. Measuring this one back here first. That's going to give us a measurement from this point here to this point here of 4 1/4 of an inch. Up here at this one, measuring from this point here to this point here is going to be 3 1/4 of an inch. Each pin is going to have a diameter of 5/8ths of an inch made from a nice steel construction, and they include these dust caps over the locks.

That way it's going to protect it to keep out any dirt, or moisture from getting in there and causing any corrosion. You're also going to notice that it comes with 4 keys. Now, the same key can work on any lock. Any key can work on any lock. They're all the same.

They use the same key system. All you've got to do is place the key into the keyhole, give it a little turn, and it's going to allow the pin to disengage from the lock. We'll go ahead and do that on both pins here. Then I actually pulled part number C45900 form our warehouse that way we can show you what these look like with the ballmount. We have it right here. This portion here will be the portion that will slide into the receiver tube of your hitch.

Once you have the pin holes lined up with the hitch on your vehicle, you'd place this pin in, and you secure with a lock. That's going to lock the actual mount to your vehicle. Remove the key, and put that dust cap on to protect the lock. Then right here, typically you would have 2 pins to hold the platform on to the mount. We leave 1 pin installed, and then we'd take this one right here, place it through the top slot, place the lock on the other side, remove the key, install that dust cap on there, and now the actual platform was going to be mounted to the channel mount, and it's going to be locked, and secured in place. That's going to do it for today's review of part number C23556. This is the Curt lock set for Adjustable Channel-Style Mount. .

This locking pin is definitely long enough for the Curt 14,000 lb adjustable ball mount. In fact, its probably about a half an inch too long. The locking part flops around a bit, I wonder if it would come off with a good smack from a hammer. I'm going to try shoring it up with a few 5/8 inch washers. 252196

EXCELLENT customer service! I did not like the extension I ordered (totally MY fault). I was able to exchange it for another type extension at no cost. This is a first class company with first class service and first class products. 452800

Really an amazing outfit. The web page provides all the detail needed to make the right choice on parts so its right the first time. The staff are friendly and caring and the delivery was spot on. etrailer is how web shopping ought to be done. They truly set the standard. 374922

by:

Though the product looks to be of good quality, the design in my opinion is poor. When the locking portion is attached to the pin(s), there is a gap between the two. This gives a purchase point to a would-be thief to get a prying tool in there. This may seem nit-picky, but this is a security lock set that is supposed to protect a trailer and hitch ball assembly. 314504

Perfect way to deter a thief from stealing your nice adjustable hitch, the pin for the receiver was long enough to use in my ‘12 2500HD 2-1/2” receiver. 593801

Locks look pretty good. Little long for me, made spacers so you can't stick prybar between lock and hitch and pop off. Easy to lock and unlock. Now I can relax when hitch is on truck and not hooked to trailer. 365447

What can I say about the locking pins? They fit. Hopefully the locks won't have to prove themselves, but there isn't a lot more to say about them unless someone tries to steal the ball or mount. Then we'll know how good they are at preventing theft. 255127

I read a review buy someone on the site to use these pins with the Curt hitch that I also purchased. Only one of them fit so that part isn't great, but the one that does fit still secures the hitch so that it can't be easily stolen/tampered with. 155902

I chose these items because they were suggested when I purchased a heavy duty ball hitch. They did not fit the hitch very well and I ended up purchasing a different locking pin for the hitch. The product is a great product and I will keep them for other applications, however, I believe a recommended item should complement the product being purchased not simply related. 109457

Ask the Experts about this Curt Hitch Locks
Do you have a question about this Hitch Lock?


  • Availability of Locking Pins for Curt Channel Style Adjustable Ballmount # C45900
  • I pulled a piece of this ball mount from inventory to take the measurement you requested. The internal width of the channel on the Curt Channel Style Adjustable Ballmount # C45900 is 3-1/8 inches. Please note that we do offer a locking pin set from Curt that is intended for use with this specific ball mount; the pin set is part # C23556. This includes two 5/8-inch diameter locking pins, each with 2 keys. I confirmed with my technical contact at Curt that use of this pin set will retain...

  • Availability of Locking Pin For Curt # C45902 Adjustable Ball Mount
  • There is indeed a locking hitch pin set, part # C23556. This part number includes two locks, one hitch pin lock and one locking pin that would replace one the retaining pins that keeps the ball assembly in place. The locks are keyed alike.
    view full answer...

  • Is Locking Pin Kit for Curt Ball Mounts C45902 and C45900 The Same
  • The channel dimensions are the same between the part # C45900 and # C45902 so the locking pins that fit one would also fit the other. For that you would be referring to part # C23556.
    view full answer...

  • Weight Capacity of Curt Locking Trailer Hitch Pin Set # C23556
  • Hitch pins like # C23556 do not have a weight rating or shear strength data because their actual capacities far exceed the abilities of the hitch or vehicle. Basically, the hitch or some other component would fail before the pin even comes close. The pins are 5/8 inch diameter steel. The straight pin has a usable length of 4-1/4 inches and the other 3-1/4 inches. The pins measure approximately 6-1/2 inches long overall.

  • Will Curt Lock Set for Adjustable Channel-Style Mounts Fit Curt Adjustable Ball Mount Receiver
  • I spoke with my contact at Curt and he confirmed the Curt Lock Set for Adjustable Channel-Style Mounts # C23556 is designed for use with Curt Channel Style Adjustable Ballmount # C45900. This part includes two 5/8-inch diameter locking pins, each with 2 keys, which will allow you to retain the full capacity of the Curt Channel Style Adjustable Ballmount. I have included a link to a video review of this ballmount for you to check out.

  • Replacement Adjustment Pins Needed for the Curt Pintle Hook with 2-5/16
  • Yes you sure can! The replacement pins that are used to adjust the hitch ball and pintle hook on the Curt # C45910-15-20 are found on our site listed as part # C45925. If you would rather go with a locking pic set I recommend the Curt Lock Set # C23556. This will replace one of those adjustment pins and then also be used to lock the shank of this ball mount to your trailer hitch receiver.

  • Replacement Pin and Clip Recommendation for Curt Channel Adjustable Ball Mount
  • For replacement pins that hold the balls of the # C45900 to the shank of the assembly we have the part # C45925 which comes with 2 pins and 2 clips. We do not have them individually though.

  • Recommended Trailer Hitch Receiver For 2017 Honda CR-V
  • We do have a trailer hitch receiver for your 2017 Honda CR-V. it is the Draw-Tite Max-Frame Trailer Hitch Receiver Class III -2 inch # 76128. This hitch has the e-coat base and powder coat finish for excellent rust protection. If you will be towing with this trailer hitch receiver, I recommend the Upgraded Circuit Protected ModuLite with 4 Pole Harness and Hardwire Kit - Includes Tester # 119179KIT. This will give you the quick connections and then you will just run a power wire to...

  • Measurement Of The Adjustment Holes On Demco Lunette Ring and Compatibility With Curt Channel Mount
  • Yes, the Demco Lunette Ring - Adjustable Channel Mount - 3" Diameter - Black - 25,000 lbs, # DM09557-81 should be compatible with the Channel Style Adjustable Ballmount - 2" & 2-5/16" Balls - 14,000 lbs, # C45900 but you will be limited by the 14,000 lb capacity of the mount for towing. The Demco lunette ring has 2 inch on center holes and the Curt mount has 1 inch on center adjustability. If you want the lockable pins, I recommend the Curt Lock Set for Adjustable Channel-Style Mounts...

  • Locking Pins for Curt Adjustable Ball Mount # C45902
  • For Curt adjustable ball mount # C45902 the locking pin set is # C23556. The pins don't have an official capacity but technically 5/8 inch diameter solid steel is going to have a capacity much higher than the hitch or vehicle. The hitch pin has a useable span of 3-1/4 inches which should be long enough for the outer width of your 2-1/2 inch hitch but it never hurts to measure to be sure.

  • Recommended Locks For Curt Adjustable 2-Ball Mount For 2-1/2 Inch Receivers
  • We can take care of securing the Curt Adjustable 2-Ball Mount, part # C45902. We have the # C23556 kit that includes a straight locking pin for the ball mount that will work on the # C45902. The additional pin included will only work with a 2-inch receiver and will not work with the 2-1/2 inch shank on the # C45902. I called my contact at Curt and they told me that this will be available in the future but is not available now. We also offer locks that will work with a 2-1/2 inch...

  • Compatibility of Curt Locking Pins on Curt Adjustable 2-Ball Mount C45902
  • Yes, the Curt locking pins # C23556 will work great for the Curt Adjustable 2-Ball Mount # C45902. I was able to go out to the warehouse and confirm the fit for you.

  • Will Curt Lock Set # C23556 Fit OEM 2-1/2 Inch Trailer Hitch on a 2013 Dodge Ram 3500
  • For the Curt lock set # C23556, the inside width of the shorter one is 3-1/4 inches, the longer one is 4-1/4 inches. The typical outside width of a 2-1/2 inch trailer hitch is 3 inches so provided that the outside width of your hitch is under 3-1/4 inches or 4-1/4 inches, this lock set will work great for you.

  • Locking Pin Recommendation for the EZ Hitch Adjustable, Steel Ball Mount AM3296
  • As long as the pin diameter matches up on your Adjustable Ball Mount part # AM3296 with the part # C23556 the locks being a bit too long would not matter. Normally we would recommend the part # AM3493, but if the Curt fits it would work as well.

  • Will Demco Adjustable Clevis Work With Curt Replacement Shank
  • The Demco Adjustable Channel mount Clevis, part # DM12676-30 is compatible with the Curt One Mount Replacement Channel Mount Shank, part # C45910. The inside dimension of the # C45910 channel mount is a little larger than 3 inches and the holes are 2 inches apart. The holes on the # DM12676-30 Demco Clevis are 1 inch apart so the channel mount will work just fine with the Clevis. If you need locking hitch pins for the mount I recommend part # C23556. These locks measure 6-1/4 inches...

  • Recommendation for Making the Channel Style Adjustable Ballmount Lockable
  • The best recommendation I can give you would be to get a Curt Lock Set for Adjustable Channel-Style Mounts # C23556. These locks are rated to handle the weight and are lockable to act as a theft-deterrent. Dimensionally the Trailer Hitch Receiver Lock # RH5-XL that you referenced might fit to hold the ball mount platform in the Channel Style Adjustable Ballmount # C45900, but since it is not rated to handle the weight it would see in that position I cannot safely recommend you attempt...

  • Recommended 7-Way Trailer Wiring Harness for 1995 Chevy C3500 with 5.7L
  • For your 1995 Chevy C3500, I recommend your start with the Tekonsha Prodigy P3 brake controller # 90195. This proportional controller will apply your trailer brakes at the same time and with the same intensity as you hit the brake pedal in your truck. It has easy to use presets and has an LCD screen to avoid code deciphering of most other brake controllers. It is completely transferable to another vehicle if you decide to move trucks at some point. If you want a more basic controller,...

  • Height Setting Adjustment of Curt Pintle Hook with 2-5/16 Inch Ball for 2 Inch Trailer Hitch
  • The Curt Pintle Hook with 2-5/16" Ball - 2" Hitches - 13,000 lbs # C45910-15-20 allows for 7 different heights within the channel. The adjustment is in 1 inch increments. This will allow for a maximum rise of 5-1/4 inches and a maximum drop of 6 inches. I recommend the Curt Lock Set for Adjustable Channel-Style Mounts # C23556 to secure both the adjustable pintle and ball but also the shank to your trailer hitch receiver.

  • What is the Tongue Weight of the Curt Forged Pintle and Ball # C45920 if Used With Curt # C45910
  • I contacted Curt and they said that the Tongue Weight of the Curt Channel Mount Forged Pintle and Ball # C45920 is the same as the shank that it is being used with. If you are using the Replacement Shank for Curt Channel Style Adjustable Ball Mounts # C45910, then your Tongue Weight will be 1,400 lbs. Keep in mind that your towing setup is only as strong as the lowest rated item that you are using. If you are using the Curt Channel Style Adjustable Ball Mounts # C45910, which is rated...

  • Recommended Trailer Hitch Receiver For 1998 Chevy K3500
  • For a 1998 Chevrolet K Series 3500 Pickup, I recommend the Draw-Tite Ultra Frame Trailer Hitch Receiver Class IV - 2" # 41901. This is an extremely sturdy hitch that is easy to install. It will fit a standard or step bumper. For a roll-pan bumper, use # 41522. For your wiring, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118315 to get a 4 way connection. Then you will want to add the # ETBC7 to get your 7 way connection along with the circuit...

  • What Trimming is Required to Add a Trailer Hitch to My 2017 BMW X3?
  • To install the Curt Class III Trailer Hitch # C13316, on your 2017 BMW X3 there is underbody trimming required, but not fascia. There won't be anything trimmed that will be visible from the back of your vehicle. Installation does require temporary removal of bumper during installation, but there is no drilling required. I've attached a video of the installation on an older model X3 for you. The installation hasn't changed, nor has the hitch receiver for your 2017 model with M Sport package....

  • Do the Balls Lock to Diversi-Tech Self-Locking, Adjustable, Aluminum Ball Mount # DTALBM6400-3S
  • On Diversi-Tech Self-Locking, Adjustable, Aluminum Ball Mount # DTALBM6400-3S the platform locks to the shank and the shank into the trailer hitch. But the ball does not lock into place. I have included a video that shows how the ball part of the ball mount works. You could go with something like Curt ball mount # D900. Then replace the regular pins with locking pins such as # C23556 to lock the ball portion to the adjustable portion and the adjustable portion to the shank.

  • Recommended Adjustable Ball Mount for 2-1/2 Inch Receiver and 15,000 lb Trailer
  • Based on your question, I assume you have the 2-1/2 inch trailer hitch receiver. There are many options available to assist with your desired towing weight, but there is one that I recommend above the others for ease of use and function at that capacity. I recommend the Curt Adjustable 2-Ball Mount # C45902. This ball mount accommodates up to a 5-1/4 inch rise or up to a 6 inch drop. It adjusts in 1 inch increments and has both a 2 inch and 2-5/16 inch ball. To secure your investment,...

We have pictures of this hitch on a 16 passenger van of other year models. You will also want the 1993 Ford Van T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118345. This will connect to your factory vehicle wiring behind the tail lights. This ModuLite connects to your battery directly to protect your factory system from overload....

  • Locking Pins Needed for the Curt Multi-Ball Adjustable Ball Mount # D900
  • The only solution that Curt offers if part # C23556 which only comes with 2 locks that are keyed alike. For your Curt Multi-Ball Adjustable Ball Mount # D900 you will want to use the Trailer Hitch Receiver Lock - Extra Long # RH5-XL to lock adjustable mount and then part # 7683 for the shanks. Since these are both DeadBolt products if you choose the "Keyed Alike" option when placing your order you will get all of them keyed alike when you place them on the same order.

There is no drilling needed for this hitch installation, but you will need to lower your spare tire for installation. If you don't already have trailer wiring, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118315 which is confirmed to fit your truck. This custom-fit T-One connector plugs into your GMC C/K Series Pickup's wiring harness, which is located...

  • When dolly towing your 2013 Hyundai Elantra, your owners manual states to set the ignition switch in the ACC posion, shift into Neutral, and make sure the parking brake is released. Failure to put the vehicle in neutral can cause transaxle damage. For a tow dolly, I recommend the Roadmaster Tow Dolly with Electric Brakes - 4,250 lbs # RM-2050-1. This dolly will allow you to simply drive onto the ramps, secure the tires in the included wheel nets, and go. You will need a trailer connector...
