HC22S is a 22 mm groove stainless steel friction stay developed for outward-opening casement windows. It delivers controlled opening, reliable support and repeatable performance for aluminum window systems used in residential, commercial and institutional buildings.
The track and link arms are produced from SS304 stainless steel and assembled with robust riveted joints. This structure improves resistance to wear and corrosion while the built-in friction pads provide smooth operation and progressive resistance, helping the sash stay where it is positioned without separate restrictors.
Offered in four sizes, the HC22S range covers sash weights up to 90 kg and window heights up to 1400 mm, making it suitable for large project openings as well as standard residential units. It is designed for OEM window fabricators who require consistent quality hardware for 22 mm groove aluminum casement profiles.
