Door and Frame Reinforcement
I thought that a good old fashioned bit of solid steel around the important bits would do the job, so I went looking and found these:-
Then during my surfing travels I came across these with their full descriptions intact, what a pleasure :)
The Birmingham Bar frame reinforcer will greatly strengthen and reinforce the door frame on one or both internal faces of an inward opening door. It is very highly recommended by crime prevention specialists, is used with existing locks and provides extremely effective additional security every time the door is closed and locked.
To reinforce wooden door frame fitted with a surface mounted rim lock or nightlatch.
Traditional wooden door frames will splinter and split open during a forced attack. A burglary victim, following a 'kick in' attack, would often find that the door frame and rim lock security had not been able to resist the attack and had failed.
To counter this problem, the police and other crime prevention specialists very highly recommend the London Bar to strengthen and reinforce the door frame around the rim lock or cylinder nightlatch. It is easy to fit, is used with existing locks and provides extremely effective additional security every time the door is closed and locked.
A packet of 2 1/2" long, No. 10 hardened steel woodscrews is supplied.
