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.

This is my second set that I have bought my son took over my first set.They are a great asset to my channel hitch.Both locks are keyed alike less keys to carry a round.And like always etrailer comes through with fast shipping and great prices.Thanks again 458448

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

We carry several different trailers for our adapted sport programs, which meant we needed to get a hitch receiver with an adjustable height. This lock worked perfectly for our situation and would buy it again for our next truck. 745223

Really great lock set. I wish that the second lock had a chamfered end on it so you could push it back on without the key in the lock. 666232

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

- C23556
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

Ask the Experts about this Curt Hitch Locks

  • 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.

  • 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.

  • 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.

  • 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 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.

  • 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.

  • 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!

  • 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...

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 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,...

  • 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...

  • 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.

  • 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.

  • 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.

  • 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.

  • Availability of Locking Pin For Curt # C45902 Adjustable Ball Mount

  • 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 # e98881 to lock adjustable mount and then part # e98880 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.

    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...

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