InfiniteRule 61180-S is for the DEMCO EZ Latch 2-5/16" ball stamped coupler. It should not be assumed to fit DEMCO cast couplers, other DEMCO coupler styles, non-DEMCO trailer couplers, receiver hitches, trailer doors, RV compartments, or storage gates. Verify the coupler brand, stamped vs. cast construction, ball size, latch shape, pin hole diameter, required span, depth, and latch clearance before ordering.
Before Starting: Confirm the trailer coupler is a DEMCO EZ Latch 2-5/16" ball stamped coupler and that the latch lock point accepts a 1/4" pin with a 2-15/16" span and 2-5/8" depth. Inspect the latch for damage, rust, or misalignment before installing the lock. Basic Use Steps: 1. Close the Coupler Latch: Make sure the DEMCO EZ Latch coupler is fully closed according to the coupler manufacturer’s instructions. 2. Align Lock Point: Locate the coupler latch lock opening and confirm the holes are aligned. 3. Insert Lock Pin: Slide the 1/4" lock pin through the compatible latch opening. 4. Attach Lock End: Install and secure the locking end using the included key according to InfiniteRule instructions. 5. Check Latch Security: Gently test the coupler latch to confirm it cannot open while locked. 6. Install Dust Cover: Seat the dust cover to help keep water, dirt, and grime out of the lock cylinder. 7. Store Keys Safely: Keep spare keys in a safe location and record the key number if provided. 8. Remove Before Towing if Required: Follow the trailer and lock manufacturer’s instructions before coupling and towing.

Confirm DEMCO EZ Latch stamped coupler compatibility before ordering.
To confirm compatibility before ordering, have the following ready: • Trailer coupler brand and model • Whether the coupler is DEMCO EZ Latch • Whether the coupler is stamped or cast • Coupler ball size, specifically 2-5/16" for this lock • Latch lock hole diameter • Required usable span and depth • Photos of the coupler latch in the open and closed positions • Whether you need a latch lock, full coupler lock, receiver lock, or door/compartment lock Why this matters: InfiniteRule trailer latch locks are application-specific. Similar DEMCO EZ Latch couplers may require different locks depending on whether the coupler is stamped or cast.
Match this lock by DEMCO coupler style, stamped vs. cast construction, ball size, pin diameter, usable span, depth, and latch clearance. Do not select it as a general trailer door or compartment lock.
If fitment or locking issues continue, check DEMCO stamped/cast coupler style, ball size, pin hole size, usable span, lock depth, latch clearance, and whether a different InfiniteRule lock model is required.
This latch lock is a theft-deterrent accessory and does not replace proper trailer coupling procedures. Always confirm the coupler is correctly latched to the hitch ball, safety chains are attached, breakaway system is connected if equipped, and all towing components are properly rated before travel. Do not tow with a damaged, mis-sized, loose, or improperly installed latch lock or coupler assembly.
