The Birmingham Bar is very highly recommended by police and security specialists to strengthen a door frame against 'kick-in' attack. It is a dual purpose flat security bar mainly used to strengthen the hinge side of the door frame on inward opening doors. If only mortice locks are fitted to the door (ie. there is no rim lock staple on the frame), the Birmingham Bar is also used to strengthen the frame on the locking part side.
On an outward opening door it can be used on the external face of the door frame on both sides. It will then resist chisel or jemmy attack to the frame but must be fitted using security screws or bolts.
Kickstop Bars are manufactured from specially rolled superior grade, 5mm thick solid steel bar with rounded sides. Each fixing hole is a countersunk hole to ensure that the countersunk screw heads can be fitted flush with the surface of the flat bar.
A packet of 2 1/2" long, No. 10 countersunk hardened steel woodscrews is supplied. If theses screws are used to fix the bar externally (as an alternative to using security screws) we suggest that the screw heads are burred over (after final fixing), to help prevent unauthorised removal.
