New design Handles

Achille : a break in terms of design, association of materials and ergonomics.

Created by a couple of young designers, Achille (registered pattern) allows the association of purity of lines and a great choice of shapes and materials. Precious wood, stainless steel colours or brushed aluminum....

Fruit of hard work of Sotralu’s engineering office (several registered patents) , Achille can bolt and unbolt Versus and Chronos locks.

Ergonomics were particularly studied.. Achille allows you in a single movement to unbolt your lock and to open your sliding window.

During all its development stage, the environmental care was taken into consideration. Achille is thus an eco-designed handle range, certified by ADEME.







HEFEL : dedicated to industrial design sliding doors and windows, HEFEL is a top-of-the-range handle which answers to the architects requirements. At once visible and invisible HEFEL looks like a wave which allows to handle door very easily.
HEFEL fits Versus and Chronos range.
