Parallel-Slide lightweight hardware
Light, Low-keyed, Long-lasting
The PSL hardware by Gretsch-Unitas is an exceptionally tight Parallel-Slide system for PVC profiles. It is particularly suitable for use in high buildings with higher tightness requirements, for sash weights up to 200 kg. The smooth opening and closing operation is mechanically actuated via the handle, increasing 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. Easy quiet movement of the PSL door due to precision-manufactured bogies with ball bearing supported rollers.
