This Brenton Bolt with Elongated Keep is designed for use with outdoor wooden gates and shed doors. Wood naturally swells and contracts through the seasons in reaction to climate conditions and this bolt is designed to allow for these slight movements as the keep is longer than the bolt is wide, so if the gate or door does move through the year, the bolt will still fit into the keep enabling the gate or door to be securely locked. Once locked, the bolt can be padlocked for extra security. This Brenton Bolt has a durable galvanised finish to prevent rust.
