The Staple (or the keep) is the metal part of the rim lock that is screwed onto the frame
The Kickstop London Bar is a door frame reinforcing bar with a 'D' shaped staple to fit over and secure the staple (keep) of a surface fitted rim lock or cylinder nightlatch. This very effective steel anti-burglary device is screwed on to the internal face of the lock side of the frame and will resist the kicking, splitting and forcing open of the door.
These genuine 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.
Genuine Kickstop London Bars are manufactured from one continual length of high grade steel - and have no unsightly welding.
A packet of 2 1/2" long, No. 10 countersunk hardened steel woodscrews is supplied.
NB: Rim locks and nightlatches are fitted at slightly different heights on individual doors. When fitting the 72" and 78" length London Bars, a little of the top or the bottom of the London Bar will probably need to be removed when fitting. The surplus can be cut off with a hacksaw.
The 'D' shaped bend in the two longer London Bars is positioned at the approximate height of where most surface mounted nightlatches should normally be fitted.
The 72" bar is approximately 6" shorter than the height of a door frame - to help minimize the need to hacksaw off a piece of the bar.
