A door alone cannot guarantee the safety of the premises. When doors are subjugated to extreme force, as in most cases of forced entries, it is more common for the lock panel to break under pressure rather than the door. While extra protection in the form of grilles and shutters can reduce this threat significantly, in some cases it may not be possible to install these. A rather simple, affordable and contemporary solution to this problem is a reinforcing strip. A reinforcing strip has a 'D' shaped staple to fit over and secure the door. This very effective steel, anti-burglary device is screwed on to the internal face of the frame and will resist force on the front panel of the door. It is available for both, lock and hinge side so that the force applied to the door is equally spread to the two metal frames.
