Review of Demco A-Frame Trailer Coupler DM15633-97


Today we're going to be taking a look at the Demco 32-Degree A-Frame Trailer Coupler. Now, the A-frame coupler's going to let you hook up your trailer to your tow vehicle. It's going to provide the connection point for your hitch ball. One of the unique features about the Demco couplers is that they feature the easy latch mechanism. The mechanism is actually an internal component and what that does is . All you have to do is drop the connection point over your hitch ball and it latches automatically, so that's where the easy latch name comes from. It's a very secure hook up and disconnect.

Again, it's going to let you hook up when the latch is in the closed position, so you do not have to prop it open. You can just drop this over the hitch ball and it's going to connect and latch automatically. Now, the handle right here. You'll notice that it's a low-profile design. The sleek low-profile design allows hazards to simply slip over the top of the coupler, which is going to prevent damage to the latch components. That's going to be a corrosion-proof polymer nylon resin composite material.

That's very strong as well as impact and corrosion resistant. Now, this is a heavy duty steel construction. It has a red powder coat prime paint finish that's going to offer excellent corrosion resistance. It has a 500 hour salt spray rating, so it's going to be great for marine applications as well. Then here at the back it's got the built in jack attachment point. That's going to allow for quick easy mounting of a round utility jack. This is a weld on installation.

It is SAEJ684 certified. I'll just give you a look of the underside of it. Just really nice structural design when it comes to this coupler. Again, this is designed for 32-degree a-frame trailers. The ball size that this will fit over is going to be a 2 and 5/16 inch ball.

This coupler's rated with a capacity of 21,000 pounds. A few measurements to go over with you real quick. We just want to go over the jack hole diameter. That's going to measure right at 2 and 3/8 of an inch. The distance between the attachment holes is going to be three inches on center. That's going to be the same between each set of holes. Center on center is right on 3 inches. Then, these holes are going to have a diameter of half of an inch. Now, you'll notice right here by the latch, there's going to be a small hole that's going to be located on each side. That's designed to patch through a coupler pin and lock. That way once you have this connected, that's going to prevent accidental disconnecting . Which shouldn't be an issue with this coupler anyways, but just adds more security. You can also place a lock on here if you're trailer's unattended to prevent somebody else from hooking up to your system. This hole right here is going to give us a diameter of 5/16 of an inch. Then, the minimum span needed for a pin lock. Basically that's going to be the usable pin length, so from edge to edge we're looking at 2 and 3/4 of an inch. Now, this is going to give us an overall length measurement, from front to back, of about 19 and 1/4 inches. Then, the width here at the back. We're looking at about 9 and 7/16 of an inch. That's going to do it for today's look at the Demco 32-Degree A-Frame Trailer Coupler.
