The Security team were out in Tooting replacing old doors that didn’t close!
This is a typically modern block communal entrance; an aluminium door with electronic V Lock bolts fitted to the frame which secure the door in two places. Locking bolts must align exactly with the door when closed for them to both operate. When they are not aligned they do not operate and the door is not secured. These types of doors don’t have door stops along the full length of the closing edge of the top as most internal doors do, the door is only stopped at the top edge by a small removable plate.
Stopping this door at this top point only, and not along the closing leaf of the door, when forced produces additional forces on the aluminium door structure as nothing at the bottom preventing this twisting. This in turn causes the v locks to move out of alignment and compromise the security of the door.
The Future Security Solution
The new steel door has 2 heavy-duty maglocks integrated to the frame. This provides as strong a stop edge along the face of the door that the door cannot pass for greater security. The maglocks provide reliable secure locking for the door. The piano hinge along the side of the doors evenly distributes the weight, ensuring no fulcrum wear over time or subsequent door dropping. The door has an internal threshold providing added strength for frame stability.
Pivot hinges – replaced by full length piano hinge
Top door stop – replaced by full length door stop
Aluminium door – replaced by steel (not able to twist through solid construction)
In frame closer – replaced by heavy-duty adjustable closer
The heavy duty closer ensures the reliable operation over time of this door with scope for adjustment to cope with weather changes in temp winter and summer which affect the closing fluid viscosity.
Happy and secure residents with no unauthorised entry to block by unsecured door.
