1. Close and latch the trailer coupler in a normal manner. The coupler must be FULLY closed!
2. Apply The Collar behind the sliding sleeve of the coupler (towards the trailer) with the hinge down.
3. Hold the sides of The Collar together to align the padlock holes.
4. Insert and lock the desired padlock.
5. Attempt to operate the mechanism and the sleeve to assure that the coupler will not open.



A drop of oil applied to the hinge before use and every few months thereafter will keep The Collar protecting your trailer for years.
