Door
Frame System
This door
frame combines several innovative features. Firstly, the frame
features a a slip lock preventer, a slot which foils attempts
to use a credit card to gain access. Secondly, a translucent
rubber strip runs the length of the door frame providing the
door frame with protection from screwdrivers, crowbars, hammers
and other burglary tools. Finally, behind the rubber strip,
the frame consists of combed sections - making a forced crowbar
opening a very time consuming and repetitive process.
