Supplied as a mirrored pair, this four-bar window friction stay uses a narrow channel track and an articulated linkage to guide a projecting sash through its opening path. Each unit has a long upper arm, two connected support links, and multiple riveted pivot points. Pressed reinforcing ribs are visible along the diagonal arms, while round and elongated fixing holes are distributed across the track and linkage ends. The two opposite-handed assemblies provide matching hardware for installation on opposing sides of a window. Four-bar hinge systems are used for casement, awning, and projected window vents.
The ribbed link arms and compact folding geometry distinguish this version from plain flat-arm friction stays. Before selection, buyers should confirm track length, mounting dimensions, fixing-hole positions, folded stack height, hinge configuration, opening direction, profile connection, and the required load target. Sash dimensions, weight, and the intended opening angle must be reviewed as part of the complete window system.
For quotation, provide drawings or samples, sash and frame profile details, left- and right-hand requirements, mounting position, finish reference, order quantity, and packaging instructions. CHIER can then assess the linkage layout and installation interface for OEM or ODM production.
