Video Transcript for Curt Lock Set for Adjustable Channel-Style Mounts Review

Speaker 1: Today we'll be taking a look at the Curt Channel Mount Lock Set, part number C23556.Without any locks, this could be you.But with our locks installed, you're safe and secure. This locking system is designed to work specifically with your Curt Adjustable Ball Mount, part number C45900, and C45902. Both locks feature a barbell style clamping mechanism that will work with either the hitch pin or the ball mount pin. Four keys are included, and any key will work with any of the matching locks. There's a dust cover on the end of each lock to keep out dirt and grime. The curved handle on the hitch pin makes for easy removal and installation.They feature a 6-1/4" overall total length.Included in the kit you'll get one hitch pin, one ball pin, and two locks.

These locks are keyed the same, so you have a total of four keys.We will start by installing the hitch pin. Remove the old one, slide in the new one, unlock your lock, slide it on, lock it up, and close the dust cover. Next, we'll install the ball pin. Remove the old pin, slide in the new locking pin. Again, unlock the lock, slide it on, lock it up, close the dust cover, and you're good to go.

Either pin can be replaced with the locking pin to secure your ball mount. Now, with our locks installed, we can feel safe knowing that our ball and our adjustable mount aren't going anywhere.That completes our look at the Curt Channel Mount Lock Set, part number C23556.

Ask the Experts about this Curt Trailer Hitch Lock

  • Will the Curt Lock Set for Adjustable Ball Mounts C23556 Work With a 2-1/2 Inch Receiver Tube
    Yes, the Curt Lock Set for Adjustable Channel-Style Mounts part # C23556 will work with the 2-1/2" receiver tube on your 2015 Chevrolet Silverado 2500. The j-style pin lock will be used in the receiver tube and the straight style pin lock will be used on the channel. The kit comes with four keys that are all keyed alike.

  • Are All of the Curt Lock Sets C23556 Keyed the Same
    I spoke with my contact over at Curt about lock set # C23556. He said that while the exact number is not known there are potentially thousands of possibilities. One thing is certain though and that is that they are not all the same!
    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.

  • 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.

  • Are the Locks in Curt Lock Set for Adjustable Channel-Style Mounts # C23556 Keyed Alike
    Yes, my contact at Curt Manufacturing confirmed that the two locks and the four keys included in their Lock Set # C23556 are keyed identically. This lock kit is intended for use in Curt's Channel Style Adjustable Ballmount # C45900.

  • 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.

  • 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.

  • How to Lock a Curt Spyder # 16085 to Fifth Wheel Rails
    What I recommend you get to lock your Curt Spyder part # 16085 to the fifth wheel rails of your truck is the Reese Pull Pin Lock Plates # RP58093 and then use a pad lock like part # 37DAT to lock the pins that hold the spyder to your rails. Check out the picture I attached to see how these products all work together.

  • Comparing Flash Solid Steel HD Adjustable 2-Ball Mount and Curt Channel Adjustable 2-Ball Mount
    The weight of the Flash Solid Steel HD Adjustable 2-Ball Mount # FA49-00-5625 that you referenced is 37 lbs, and the weight of the Curt # C45902 is 36 lbs. So in that regard they are essentially the same. They really are quite a bit alike in most ways. Same capacity at 20,000 lbs, both fit 2-1/2 inch hitches, both can do same amount of drop at 6 inches, both are highly reviewed by our customers, and both have very similar prices. I'd say the edge goes to the Curt though since it has...

  • Can You Add a Pintle Hook To the B&W Tow & Stow 3-Ball Mount for 2-1/2 Inch Hitches
    I do have options for you but there is not a pintle hook adapter for the B&W Tow & Stow 3-Ball Mount part # BWTS20048B so the only way to obtain a pintle hook with the Tow & Stow feature is to purchase the B&W Tow & Stow Pintle Hook with 2-5/16" Ball part # BWTS10056 separately and then use the B&W Hitch Receiver Reducer Sleeve part # BWRHXA2182 with this. That said, if you purchase the Curt Pintle Hook with 2-5/16" Ball part # C45908 and the Replacement 2" and 2-5/16" Dual-Sided Ball...

    The Curt Channel Style Adjustable Ballmount - 5-1/4" Rise, 6-3/4" Drop - 6,000 lbs # C45901 has a shipping weight of 15 lbs whereas the MaxxTow Adjustable-Height Ball Mount - 2" Hitch - 10" Drop, 8" Rise - 5,000 lbs # MT70067 has more adjustability but less capacity and has a shipping weight of 14 lbs. Finally, the MaxxTow Adjustable-Height Ball Mount - 2" Hitch - 7-1/2" Drop, 6-1/4" Rise - 5,000 lb # MT70068 falls between these two with adjustment ability but still has a 5,000 lb capacity....

  • Recommended Locking Hitch Pin and Adjustment Pin for Anderson Aluminum Rapid Hitch
    The Rapid Hitch Trailer Hitch Lock and Adjustment Pin Lock Set for 2" and 2-1/2" Hitches # AM3492 is what you were describing. The locking pins are 5/8 inches and have an inside width of 4-1/4 inches. If you want a different brand I recommend the Curt Lock Set for Adjustable Channel-Style Mounts # C23556 which will have that same 4-1/4 inch span and give you a keyed alike adjustment lock and hitch lock. I've attached videos of this product to assist.

  • Keyed Alike Hitch Locks for 3" and 2" Receivers
    The Curt Lock Set for Adjustable Channel-Style Mounts part # C23556 will do the trick. These pins are rated as high as any hitch and ball mount will be. The Longer one has a usable length of 4.25" while the shorter is 3.25" which will be great for your 3" and 2" receivers. While it is not the typical solution it is the only keyed alike option I currently have available. (May 2020)

  • Is There a Locking Ball Mount Rated for Over 10,000 lbs?
    The only B&W Tow & Stow ball mounts we offer that have a towing capacity over 10,000 lbs and fit in a 2" hitch use a pintle hook, like # BWTS10055. There are adjustable ball mounts from other manufacturers that fit in a 2" hitch and can give you the capacity you need. The MaxxTow Adjustable 2-Ball Mount # MT70380 is one of those options as it has a 12,000 lb capacity with the 2-5/16" ball and offers a maximum rise of 7-7/8" or maximum drop of 6-1/4". Should you need more rise or...

  • How To Add a Pintle Hook to the Curt Adjustable 2-Ball Mount
    In order to add a pintle hook to the Curt Adjustable 2-Ball Mount part # C45902 that you have now all you will need to obtain is the Curt Pintle Hook with 2-5/16" Hitch Ball part # C45922. I would also recommend you use the Curt Lock Set for Adjustable Channel-Style Mounts part # C23556 on this setup as it will be a bit more valuable than the standard hitch ball. The Curt Pintle Hook with 2-5/16" Hitch Ball part # C45922 is not offered without the hitch ball attached.

  • Locking Pin Compatible with BWGNC4250 Gooseneck Coupler
    The B&W Defender Locking Gooseneck Coupler Inner Tube - Round - 2-5/16" Ball - 25,000 lbs # BWGNC4250 would require an incredible lifting height of the trailer steadily straight up to release a trailer when locked at the coupler to the hitch ball. That is the only reason it doesn't come with the locking pin you referenced. The InfiniteRule Hitch Lock for Gen-Y Gooseneck Coupler w/ 4" Round Tube - Stainless Steel # 34065041 would be a great fit. It is a 3/4 inch diameter lock that has...

  • Increments of Drop for Curt Channel Style Adjustable Ball Mount
    The Curt Channel Style Adjustable Ball Mount # C45901 adjusts in 1 inch increments, with it's maximum drop being 6-3/4 inches, and you can then go to 5-3/4 inches, 4-3/4 inches, or 3-3/4 inches depending on what you need. This ball mount comes with a pin and clip but you can lock the mount with the Curt Lock Set for Adjustable Channel-Style Mounts # C23556. For a hitch ball, the corrects fits are 1-7/8" Hitch Ball # C40002 and 2" Hitch Ball # 63845. I have added a link to a video...

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...

  • 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...

    For your 2017 Jeep Grand Cherokee, to go with the Curt Trailer Hitch Receiver # C13065 you chose I recommend the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118727. This harness plugs into your Jeep Grand Cherokee's wiring harness, which is located behind the tail lights on both the driver's side and passenger's side.

    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,...

    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.

  • 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.

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...

It is a 2 inch receiver opening, so it will be compatible with many accessories as well as ball mounts. This is rated for the same capacities when using weight distribution which I do recommend if you are towing that much weight. For your ball mount, I recommend the Curt Channel Style Adjustable...

If you are using the Replacement Shank for Curt Channel Style Adjustable Ball Mounts # C45910, then your Tongue Weight will be 1,400 lbs.

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 is completely transferable to another vehicle if you decide to move trucks at some point. If you want a more basic controller,...
