This coupler lock provides security for your RV with a patented design that won’t false-lock or pop open. The barbell-style lock adjusts to fit both 1/2 and 7/8 inch coupler latches without tools.

Triple-plated chrome finish with internal o-ring seal protects the locking mechanism from dirt and corrosion, whilst the hardened 7-millimetre steel shaft resists forced entry.
