Quick-release security for your 3-1/2-inch coupler latch. This barbell-style lock from Trimax opens and closes with a simple quarter-turn, eliminating fumbling with keys or combinations at the campground.

The patented steel lock head features an internal O-ring seal and watertight cap, keeping dirt and corrosion at bay even during extended storage. The hardened 7mm shaft resists prying, and the triple chrome-plated finish protects against rust.
