This adjustable barbell coupler lock secures trailer couplers with a design that accommodates five different locking positions, making it compatible with lever-style couplers across a wide size range. A double-entry automotive-style key provides convenient access from either side, while all-weather grips and a sealed lock housing protect the mechanism from moisture and corrosion.

The nickel-chrome plated finish adds durability and visual appeal, and the conical housing and knob design create a flush fit against the coupler side walls for security and comfort.
