How it works
The bracket allows for windows to be fitted immediately when the apertures are ready.
It can be fitted onto the windows in the PVCu factories reducing installation time onsite, allowing for factory quality fitting or can be fitted onsite.
The window can then be placed into the aperture and set into place and secured.

The benefits
Reducing water damage, securing the property immediately.
Enhanced fire protection and security. Added security may lead to reduced insurance costs.
Increased site productivity by allowing internal and external trades to start as soon as the frame is erected.
Construction programme should be reduced by approximately four weeks.

The load bearing test was carried out with a window using 6 window brackets at full extension. An additional 203kg was added to the window and left to hang for 72 hours the window drop was less than 3mm.
The bracket is made from ferritic stainless steel, zinc alloy, copper nickel chrome plated and a grey acetal homopolymer.
Normal operating temperature is -20°C to +60°C.
Materials used will not degrade,
due to ultraviolet light or when using neutral acidity non-solvent cleaning chemicals, at a rate faster than other parts of the window assembly.
