Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
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.

Health issues have prevented me from using it. Hoping 2023 is a better year.

These types of locks normally dont work. The Curt locks work and still work even now after a year I have not sprayed oil on them, there is no need, they are still in great shape! I highly recommend these locks

Perhaps some lubrication is needed for a smooth entry. Next time, if you want to try a barrel key like item # BD580400, they are easier to maneuver in my opinion.

I have used these items quite a bit over the last year and I am pleased with them. The only concern I have is that they dont seem to be a very strong locking mechanism. I feel like it wouldnt take much to pry off the lock. But so far no one has stolen my drawbar.
