How do I properly hook up and disconnect my boat trailer using a Demco EZ-Latch coupler?
Hooking up and disconnecting your boat trailer with a Demco EZ-Latch coupler is a quick and tool-free process—ideal for solo launching or retrieving your boat. The EZ-Latch design automatically engages the hitch ball, improving safety and convenience, especially on boat ramps or uneven surfaces.
To hook up your trailer:
- Position the trailer coupler directly above the correct size hitch ball on your tow vehicle.
- Lower the trailer tongue using the jack until the coupler fully seats over the hitch ball.
- As the coupler lowers, the EZ-Latch system auto-engages—you don’t need to lift the handle.
- Check that the coupler is fully latched (the handle will return to a down-forward position).
- Attach your safety chains, crossing them underneath the coupler for added security.
- Connect your trailer wiring harness and test all lights.
- Optionally, insert a coupler lock through the latch hole to deter theft.
To unhook your trailer:
- Chock the trailer wheels and ensure the tow vehicle is on level ground.
- Disconnect the safety chains and trailer wiring.
- Use the jack to lift the trailer tongue until the coupler clears the hitch ball.
- As you lift, the EZ-Latch will automatically release—no need to manipulate the latch.
Important: Always confirm you’re using the correct hitch ball size and secure all connections before towing. For safety, do not exceed the weight ratings of your coupler or tow vehicle.
