The Problem

This is typical a modern block communal entrance aluminium door it has electronic V Lock bolts fitted to frame which secure this door locked in two places. Locking bolts must both align exactly with door when closed for them to both operate. When they are not aligned they do not operate and the door is not secured at that point. These type of doors don’t have door stops along the full length of the closing edge or the top as most internal doors do. Door is only stopped at top edge by small removable plate .

Door Stop Plate

This is the small stop which is the only part stopping this outward opening door from opening inwards. Stopping this door at this top point only and not along the closing leaf the door when forced produces additional forces on the aluminium door structure as nothing at bottom preventing this twisting. This intern causes the v locks to move out of alignment and compromise the security of the door.

Easy Install
Long Lasting
The Final Solution

This 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 which 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 of this steel door ensuring no fulcrum for wear over time, and door dropping. This door has 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
Heavy Duty Closers
