Box flush bolts are used on double leaves timer doors when one door is usually kept inactive, the hinges are located on the outside while the flush bolt is installed on the inside to help hold the door in place. Our flush bolts are available in a range of sizes from 200mm -1000mm, to suit all varieties of doors.
Extension flush bolts are installed into the edge of the door and have a toggle lever that is moved up and down to push the attached rod and bolt into a header or threshold (footer), which locks or unlocks an inactive door. Our extension flush bolts are available in a range of sizes from 300 - 1000mm
The dust proof socket is installed as a set with a flush bolt, it is installed in the floor and acts as the socket for the flush bolt to lock into. The mechanical top lid keeps the socket dust free while not in use, deterring any debris from entering the socket and causing internal damage.
