Video Transcript for Curt Adjustable Trailer Coupler - Coupler Only - C25329 Review

Speaker 1: Today we're taking a look at a CURT Channel-Mount Coupler. This coupler lets you hook up your trailer to your tow vehicle, provides a connection point right here for it too, 5/16th inch hitch ball and it mounts to trailer channel bracket with the included hardware.This is compatible with CURT Channel Brackets, part number C48610 and C48650. If we take a measurement of that bracket real quick outside edge to outside edge, it'll show us that it will also work with any standard three inch channeled racket.Now, the channel mount design is a really great feature. It allows for easy height adjustment so that way you can adjust the coupler height to match different tow vehicles and that really always ensures that the towing set up is as level as possible, which is the safest way to tow.When it comes to the construction, we're looking at a solid neck design for increased strength. It also has a durable black powder-coated finishing on the unit to resist rust and corrosion and it is constructed from heavy duty die cast steel.Right here is the sleeve lock latch system. Now, this system ensures a nice, tight fit around the hitch ball for a very secure connection and it does come with a coupler pin, if you want to replace that with a coupler lock, you can do that as well.

A coupler lock's not included, it is sold separately and we have multiple of those available at etrailer.com.But when you're ready to connect to your 2 5/16th inch hitch ball, what you would need to remove the pin. It is tethered on there with a chain so you don't have to worry about misplacing that or losing it. Then you take this collar and you simply just slide it back and as you do, this piece over here will kick open, that's spring-loaded. That opens up the socket to accept a 2 5/16th inch diameter hitch ball. Then you can connect this, drop it over the hitch ball, pull this back again, push that in and then the sleeve can slide back up and it's secured.

Then you want to replace the pin and clip or again, if you want to use a coupler lock, you can do that as well. It's a nice, easy system to use. Again, very secure with the sleeve lock latch system.I did take a measurement from the center of the mounting holes to the front edge of the coupler, it's got a measurement of around 9 7/8th inches. The mount holes are separated on center by two inches. This does have a capacity, according to the CURT sticker right here, of 12,000 pounds and a tongue weight capacity of 1,875 pounds.If you want to upgrade or replace this pin and clip with a pin and lock, few things that you need to know, that pin hole diameter is 5/16th of an inch so you want to make sure that your lock diameter does not exceed that and you'll need at least a 2 1/4 inch span or usable pin length, at least 2 1/4 inches is needed if you want to upgrade or replace this with a coupler lock.That's gonna do it for today's look at the CURT Channel Mounted Coupler..

Broke my coupler and needed a replacement. This was an identical match. The trailer company must get their couplers here too; It's that exact.

  • What Type of Lock Can Lock Curt Channel Mount Coupler # C25329 to Hitch Ball
    For a pin lock that fits as a replacement for the snapper pin of the Curt coupler part # C25329 that you referenced we have the etrailer.com lock part # e98888 which will fit and work well. This will prevent the collar from sliding back to allow the coupler to open. I attached a review video for this for you to check out as well.
