Grundig Trailer Coupler Lock for 1-7/8", 2" & 2-5/16" Hitches - Aluminum Hitch Lock with 2 Keys, Fits RV, Boat & Utility Trailers - Black

I. Product Overview When a trailer sits unhitched in a driveway or storage lot, the coupler is what connects it to any other vehicle. This lock closes the coupler, so it stays locked until you open it with the key. One lock covers the three common coupler sizes found on travel trailers, boat trailers, utility trailers, and off-road trailers — in black, red, or yellow. II. Product Features One Lock, Most Trailers: Covers the three common coupler sizes, so you don't need a separate lock for each trailer. Aluminum Body, Brass Cylinder: An aluminum shell with a brass lock core that keeps working through rain, dust, and road spray. III.

Precautions Test the Fit First: With the trailer unhitched, install the lock and confirm the coupler latch will not open.
