Window Fixing Straps For Fitting UPVC Windows

Strong, adjustable steel fixing strap for standard and extra wide reveals

The Cavalok universal window strap is a robust steel component designed to fix windows quickly and securely into cavity walls of all sizes. The universal strap is compatible with 70mm plastic window systems, and is the ideal way to fix windows in place on new-build or replacement projects.

Clip and lock for secure window fitting
The steel strap clips and locks onto the outer window frame, with no need for screws or fixings. Once the window is positioned in the building aperture, the strap is simply screwed to the interior blockwork to secure the window in place.

Adjustable strap fits even the widest wall cavities
At 250mm long, the Cavalok universal window strap is one of very few on the market designed specifically for today’s wider cavity sizes. The final 50mm of the strap can be removed to create a shorter strap suitable for more conventional cavities up to 100mm wide. The window fixings are perfect for rapidly fitting uPVC windows.
