Specs:
This coupler features a simple-to-use latching mechanism known as the eZ-Latch. With this mechanism, hooking up is as easy as dropping the coupler over your trailer hitch ball. The latch does not need to be tugged or manually activated to allow the ball into the coupler socket, nor does it have to be secured in place. Just make sure that the coupler is properly lined up with the ball when you lower it, and the rest is automatic. Disengaging the coupler is just as effortless. Simply lift up the contoured handle and the coupler socket will automatically release its grip on the ball.
Sturdy, Corrosion-Resistant Construction
Made of sturdy steel, this straight-tongue coupler with a shortened body features a durable zinc coating that is designed to limit rust and corrosion. This finish has a 200-hour salt spray rating. The eZ-Latch's sleek, ergonomically designed handle is constructed of a durable composite material that's corrosion-proof, allowing it to withstand whatever the road and the elements dish out.

Glad to hear that worked out so well for you. That’s a pretty big upgrade from the old style couplers, and not having to worry about forgetting to latch it is a huge peace of mind. That’s a great photo too, everything looks clean and solid. What kind of trailer are you running that setup on?

For the Demco # DM13689-95 eZ-Latch coupler, we recommend the # e98887 which would install into the hole that is on the side underneath the top latch.

The pin hole diameter for the DM13689-95 coupler is 5/16" and the pin should span at least 2 1/2" to fit. The most common trailer lock for this coupler is the etrailer Surge Brake Coupler Lock - 3-3/8" Span - 1/4" Diameter part # e98888. Since this is only a 1/4" in diameter it should easily fit into the 5/16" hole on this coupler! If you try out this pin let us know if you're still having difficulty locking the coupler.
