Video Transcript for Curt Squeeze Latch Channel-Mount Coupler Review

This right here is the CURT Adjustable Trailer Coupler. So this is gonna fit your channel like this. If you have one on your trailer already, great. If you don't, we do have some in our warehouse over there. So you can add it to your cart if you decide to go with this style coupler. What you wanna make sure of if you already have it on your trailer is the interior width of the channel, you wanna make sure it's gonna be three inches wide, the holes need to be 5/8 of an inch in diameter, and they need to be spaced out two inches from center to center.

Our coupler's made of a heavy-duty steel construction, black powder-coated finish, so it's not going to rust away and seize up over time. This is going to be pretty high up there when it comes to weight capacities, gross trailer weight, 15,000 pounds, and the tongue weight is gonna be 2,250 pounds. And you wanna make sure that you have a 2 5/16 inch ball, which that is what this coupler is gonna work with. To hook up to your trailer, we wanna take this pin here. I like how it has this little tab, so it's pretty easy to get undone.

We wanna pull that out, and you don't have to worry about putting it anywhere 'cause it is connected via chain. I lose things and I appreciate it when I can just drop it and it stays there. And then, this is a squeeze latch. So what this is gonna do, you're gonna squeeze on it and push it forward. It's gonna catch itself right there.

So if we we're to hook up a ball, go like this, go up like this, you can hit it like that and you're all connected up. And you do wanna make sure to replace this pin whenever we're done, find the hole, put it in there, snap it into place. To disconnect it, do the same exact thing in reverse order pretty much. You just pull this pin, bring this up, and you're good to go. As far as mounting this, it's pretty easy.

As long as you have the channel with the right dimensions, it's gonna work. The hardware is included, and you can see the pretty color of it, this is grade eight hardware, so it's gonna be a little bit harder than the grade five and all the ones underneath of it. So they did give you a nice hardware. Some of it does not, some of these couplers don't come with hardware, this one does, you have a lock nut, a washer on both sides, and you're good to go. All you need is a 24-millimeter socket and wrench to tighten 'er on down. Let's see how much length it's gonna add to your trailer from the very, very edge of our channel to the very end, it's gonna be about 7 1/2 inches. And then, from the center of the mounting holes to the center of where our ball's gonna be, right about here, that's gonna be about seven inches. It comes with the hardware, which it's nice, you don't have to grab that separately. But there is one thing I do suggest that you get, and this is for all your trailers, and that is a lock. So there's two different ways we can do it. One, we could do a pin-style lock, which we have one that is designed for multiple, different spans, so it's gonna fit through this one pretty easily, but you can use it on all your other trailers. If you're at a construction site or you're leaving your trailer outside, you want it to be there when you get up and you need to use it, so you can use the pin style to lock multiple, different types of trailers if you wanna do it that way. Or there's another one that actually goes right around here and covers this whole entire area, so no one can even attempt to try to hook up and chain it up. So those are two things that I definitely recommend with any trailer coupler. If you're looking for a heavy-duty trailer coupler for your trailer because you're hauling some heavier equipment, this is gonna be on the higher end of that, we have one that's exactly the same. It's the etrailer one, that's gonna be a little bit more cost effective. But this is a heavy-duty coupler for heavy-duty stuff, and it's nice that you can adjust it within our channel. So I do think that the CURT Adjustable Trailer Coupler is gonna be a great option for you..

See what our Experts say about this CURT Adjustable Trailer Coupler

  • Does Curt Channel Mount Coupler # C25328 Fit Standard Channels
    In general yes, the channels that the channel mount coupler like part # C25328 attach to are all the same dimensions.
    view full answer...
  • Will the Curt Channel-Mount Coupler Fit a 1-3/4" Hole Spacing
    The industry standard for channel couplers is 2" spacing (center to center) with 5/8" holes. If you have something different then we would not have options for this and therefore I recommend simply welding on a new channel with standard spacing such as the Curt 3-Position Adjustable Channel Bracket part # C48610 which matches up with the Curt Channel-Mount Coupler part # C25328.

  • Can 2" Coupler Be Installed on a 13K GVWR Dump Trailer
    Standard 2" hitch balls are going to cap out at about 10K - 12K for weight. Since it sounds like your trailer can weight up to 13K you really need to stick with a 2-5/16" hitch ball for safety reasons. If the issue is having a ball mount with just a 2" hitch ball then I recommend getting a combo kit ball mount like the BulletProof Hitches 2-Ball Mount for 2" Hitch # MD204. This comes with a 2" hitch ball rated for 10K as well as a 2-5/16" hitch ball rated for 14K.

  • Recommended Lock for Safety Pin Hole on Curt Channel-Mount Coupler
    The Curt Channel-Mount Coupler # C25328 has a 5/16" diameter pin hole. You can use a lock like the etrailer Adjustable Trailer Coupler Latch Lock # e98883. This has a 1/4" diameter with a 2-1/2" span and 5 locking positions. It also has a steel construction with the plastic cap for the key slot to prevent corrosion.

  • CURT Adjustable Trailer Coupler Latch Lock Recommendation
    For a pin lock that would fit the pin hole of the Curt Channel Coupler part # C25328 you could use the Adjustable Trailer Coupler Latch Lock part # e98883. Once installed this would prevent the latch from opening.

  • What Size Channel Does the Curt Channel-Mount Coupler part # C25328 Fit
    The Curt Channel-Mount Coupler - Squeeze Latch part # C25328 is designed to fit channel mounts that are three inches wide inside if the channel like the Curt 3-Position Adjustable Channel Bracket part # C48610. If your current channel measure three inches wide inside the channel this is an excellent choice.

  • Width of the Curt Channel-Mount Coupler
    The Curt Channel-Mount Coupler part # C25328 is designed to be used with an adjustable channel such as the Curt 3-Position Adjustable Channel Bracket part # C48610 which has an inside width of 3". Therefore, the width of the but end on the coupler is 2-7/8". The mounting holes are then spaced 2" apart on center.

  • Is There a Difference Between Curt & etrailer Adjustable Channel Mount 15k Coupler
    The only difference between the Curt Channel-Mount Coupler - Squeeze Latch - 2-5/16" Ball - 15,000 lbs # C25328 and Trailer Coupler - Adjustable Channel Mount - Squeeze Latch - Black - 2-5/16" Ball - 15,000 lbs # CTA-280 is the manufacturer. Curt makes the # C25328 while Ram makes the # CTA-280, but and while neither is made in the USA we do have an option for that if you'd like.

  • Could Bulldog and Curt Channel Coupler Fit in Lock N Roll Channel
    The channel of the # 336TS505 is wide enough to accommodate the # BD028585 and # C25328 and the hole spacing is correct at 2 inches and hole diameters are 5/8 so it would work well.

  • Recommended Coupler Lock for Curt Channel-Mount Coupler
    Based on the lip on the Curt Channel-Mount Coupler - Squeeze Latch - 2-5/16" Ball - 15,000 lbs # C25328 you will be unable to use the # e98895. The # e87ZR might fit, but I would question how secure it is once again based on the lip on that coupler. Instead, I would recommend the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-316. This is a universal lock that will secure over the top of the coupler and uses a bolt-blocked locking system to prevent...
