Coupler And Extensions - specification

The colours shown are designed as a guide only, if colour accuracy is vital please ensure you have seen a foil swatch before making your final selection. 

We provide both our Couplers and Extensions in a range of different colours, in order to match with the colour of our windows.

Our couplers come in a range of sizes.
They can be cut to a smaller length as desired.
Remember to reduce the width of the shorter window by 5mm to allow for the Coupler - we will not make this allowance.
Please note, screws are not supplied with Couplers.


Our on-line design tool uses a simple step-by-step process to produce an instant quote for the uPVC windows and doors you want, in just a few minutes. You won't find the same quality product, level of service or price to match - If you do we promise to beat it*.
