With hardware for Projecting Top-Hung, Parallel-Projecting, Horizontal-Pivot or Turn-Only windows, as well as special designs based on individual customer specifications, it is possible to satisfy demands for new methods of opening and window shapes with unique aesthetic qualities. The range of services extends from technical planning and design through to production of the special parts and handling of projects together with customers all over the world.

Parallel-Projecting hardware

The special solution for sashes which weigh up to 400 kg. that open up to 250 mm and the sashes are up to 5,000 mm. Parallel-Projecting windows can be created with a comprehensive range of GU stays for all frame materials, such as wood, PVC and aluminium.

Hardware for Turn-Only windows

Projecting Top-Hung hardware

This hardware range offers a number of different Projecting Top-Hung stays with an opening angle from 20° to 50°. Sashes can be made up to a height of 2,500 mm. Projecting Top-Hung windows can be made with GU stays for all frame materials, such as timber, PVC and aluminium.
