Extra UPVC reinforced couplers / joiners

The easiest way to unite separate windows and doors is using a coupler. Our couplers are aluminium reinforced as you can see from the diagram below.

To attach just knock on with a rubber mallet, the side clips will join securely with the window/door frame.

Please note: allow space for the coupler's width, by reducing your windows/doors by 15mm.
