GATEMASTER BSKS Security keep for Superlock with interlocking tab

Gatemaster BSKS Superlock interlocking keep The clever interlocking design of this keep means that the gate cannot be levered off the post once the gate is closed. One section bolts in front of the lock and the post bracket is easy to fit with the two expanding fasteners. Requires a minimum of a 38mm gap between the gate and the post.
