The Design and Technique

Design-A-Flange is very compact in its design and very easy to install. Just put the inserts together, place them in the frame and install. The inserts lock on to each other as well as to the frame, ensuring a safe and secure installation.

Fiberglass re-inforced Polypropylene is used for the frame and the inserts, ensuring a very rigid structure. The soft TPE lets us incorporate push-out membrane seals with exceptional sealing properties. The two materials together with our patented system make it possible to have a flange system with a very slim design.

Design-A-Flange is made to have very low protrusion and will take up very little space. This allows for very discrete and aesthetic installations. You can even have cable anchorage on your cables by using our KLIKSEAL and you will still have an installation that takes up a minimum of space.

Design-A-Flange is available in the sizes that are most commonly used on the market today. The system is continuously growing and we are sure you will find a version that suits your needs.

Now you are able to choose yourself - You decide!
