Choose Your Fixing Type
Reveal Fix
The security-bar frame fits inside your window opening.
Measure the width and height of the opening in three places, using the smallest measurements. Deduct 10mm from the overall width and height to allow installation clearance.
Face Fix / Plant On
The security-bar frame mounts onto the outside face of the wall, overlapping the window opening.
Add 100mm to both the opening width and height to provide approximately 50mm overlap on each side.
Face fixing costs an additional £60.
