17 COUPLERS Step The EZ Latch coupler remains in its locked position. No need to open the coupler. Simply back under the coupler and start lowering it onto the ball. Step 2 The coupler will automatically open to accept the hitch ball into the coupler socket. Step 3 Once the trailer is completely lowered, the coupler will automatically lock around the hitch ball. Demco s exclusive EZ Latch coupler design automatically latches when dropped onto a hitch ball. SAFETY - All Demco EZ Latch couplers exceed all required SAE J684 safety standards without the use of a safety pin. SECURITY - Never forget to latch your coupler again. Let our EZ Latch system bring you peace of mind when hooking up your next trailer. MAINTENANCE FRIENDLY - The EZ Latch System is a maintenance-free system. NO grease or adjustments needed. VARIETY - EZ Latch couplers are available in a variety of styles and weight ratings: channel mount, tube mount, and A-frame from 0,000 to 2,000 lb. G.V.W.R. The EZ Latch coupler is offered in an array of different hitch mounts in both 2" and 2 5 /6" ball coupler sizes MOUNTING CONFIGURATIONS INCLUDE: Weld on or bolt on 3" tongue tube Weld on or bolt on A-frame Bolt-on adjustable height channel mounts Make sure your next coupler has the EZ Latch Advantage for a safe, secure connection the first time, every time.
