The new Parallel-Slide lightweight hardware by Gretsch-Unitas

The Parallel-Slide lightweight hardware (PSL) from Gretsch-Unitas is an exceptionally tight Parallel-Slide system for PVC and aluminium profiles, and lately for timber profiles as well. It is particularly suitable for use in tall buildings requiring a high degree of tightness.

The strikers secure the frame cams in all important positions. A ventilation position in which exhaust air flows out and fresh air flows in can be reached when the handle is in the horizontal position. The frame cams are in the secure position in the striker and also in the ventilation position.

The smooth opening and closing operation is mechanically actuated via the handle, facilitating ease of use and preventing mishandling. When closing, the sash is pressed against the frame with the two circumferential sealing layers, resulting in a very high tightness.

The gasket pressure can be adapted to the individual installation situation via the frame cams. If the sash and/or frame is deflected, the frame cam can also be adjusted at a later point.

Easy quiet movement of the PSL door due to precision-manufactured bogies with ball bearing supported rollers.
