Download Specification

The window shutter frame is formed from 6mm thick rolled steel angle with fully welded corners and is designed to house a 915mm x 915mm aluminium framed sliding window as standard.

3mm thick mild steel pressed shutter leaves are welded to the frame with full length continuous pre galvanised piano hinges complete with a stainless steel pin which allow the shutters to open and close freely. When closed two spring bolts fitted to each shutter leaf are used to secure the leaves at the top and bottom of the frame whilst the interlocking leaves are protected from jemmy attack by a central 5mm tee-bar. An additional fifth spring bolt locks the shutter leaves together for additional attack protection and to complete the creation of a highly secure locking mechanism.

Externally the shutter provides an aesthetically pleasing flush finish with innovatively designed security features to increase resistance to attack. When open each leaf of the shutter can be held in position using the anti-luce retainer.


A revolutionary design combining an innovative and highly secure
locking mechanism with an attractive flush external appearance
