Who It's For

This lock is well suited to RV and trailer owners who need a visible, heavy-duty deterrent for parked or stored trailers, campers, and boats. It particularly benefits people who frequently leave trailers unattended at campsites, marinas, storage lots, or when parked at home.

It is less appropriate for owners who require an ultra-lightweight or covert quick-release device, or for those with nonstandard coupler sizes; buyers should confirm they have a 2 5/16 in coupler before ordering.
