What makes a door a door? A door needs hinges and a way of keeping it closed, however that may not be all. Depending on the type of door it may not need a lock at all, but may need other hardware to make it compliant or fit for use. This short guide will give you a rundown of the products your doors in the workplace may need
As the name suggests DOOR CLOSERS are used to keep doors closed. This could be on a shop front to keep the weather out or to prevent the movement of smoke and fire. Door closers come in a range of forms including Concealed, Under floor, Automated and Overhead. Door closers also vary in power, control and adjustment depending on cost. Automated closers operate using a range of methods including motion detectors, Exit buttons and even the sound of a fire alarm.

BARS AND PLATES are used to secure doors. The Birmingham Bar runs around the frame and is designed to reinforce the frame against kick in attack. The London Bar Runs along the keep side (where the lock meets the frame) of the door, again to reinforce the door against kick in attack. Anti fish (also known as Anti thrust plates) run along the opening edge of the door and stop the lock being tampered with from outside.
