Jacks & Couplers

Demco Couplers

Diamond C offers adjustable DEMCO couplers as standard on all of our bumper-pull trailer models. Demco’s unique EZ latch design automatically latches when placed over a hitch ball, and are entirely maintenance-free as their couplers don’t require any greasing or adjustments. Demco cast couplers are made from sturdy steel and feature a durable primed finish.

We offer 3 Demco couplers (depending on the trailer and the selected GVWR package).
