Purbrook GT
Perimeter security starts with the gate. Unlike traditional door hardware, gate locks must accommodate larger clearances, harsh outdoor environments, and demanding security requirements without compromising reliable operation.
The Purbrook GT is purpose-built for these challenges. Its 1½-inch (40 mm) bolt throw accommodates typical gate tolerances while automatically securing the opening upon closure. Supporting mechanical key entry, electronic access control, and multiple egress options, the Purbrook GT delivers dependable security for government, utilities, data centers, and other critical infrastructure facilities.
