Door Frame Kits

Double Glazed Sections

We provide double glazed door frame kits which perfectly match your wall system.

We supply PRO-office DG double glazed door frame kits custom machined to your specification and complete with everything you require to install the door frames quickly.

We provide double glazed door frames, handed or universal, depending on your requirements. Our kits contain the necessary hinges, the correct strike plate depending on if it is a glass or timber door that you are installing, gaskets and brackets - all packaged in a specific way, ensuring they arrive safely.

Rapid Fit

When you order your frames, we will produce a unique fabrication drawing to ensure that your order's door frame is to your specification. As standard, we hold our double glazed door frame profile in stock in 4 primary colours: Anthracite Grey RAL7016, White RAL9010, Grey RAL9006 and Black RAL9005. We do this to ensure a fast turn around while reducing the need for you to order way in advance or hold stock. Our standard delivery for door frame kits is 3 – 5 working days from receipt of order. We also supply our door frame sections custom painted to any of the colours in the RAL product range. If you would like something special, we also provide door frames which are anodised.

The kits are designed in a way to allow you to install them quickly. Our standard door frame profile will enable you to glaze straight out of the back of the frame with an aperture depth of 12.5mm. However, due to continuous product development, we have also introduced a deep fill door frame with a glazing depth of 17.5mm.


Our door frame kits are custom fabricated to your exact requirements, and we include all the necessary fixings for a fast and accurate install. Short delivery lead times are guaranteed thanks to our sizeable stockholding.
