The glass is secured to the panel profiles from both bottom and top with a special four-point lock system. The elegant glazed surface is achieved without interruption from any panel profiles and the black-anodized profile behind the glazing gives the system a harmonious look.

The roller technology enables smooth and easy operation of the panels and the small plastic guides bring the panels securely into the 90° parking position.

Concealed fixings and frameless glazing create the elegant look of the system and set GSS 17 apart from its competitors.

A simple spring connects the handle directly to the operation mechanics in the panel profile.  It combines comfortable usage with long-lasting durable components.

A 90° rotation unlocks the active opening panel and allows it to operate like a door.
