Compact Four-Bar Window Friction Stay with Black End Stop

This compact four-bar window friction stay uses a narrow channel track and an articulated arm set to connect a projecting sash with its frame. Four-bar friction stays are used to support projecting sashes and provide frictional control during movement. The visible assembly includes a long upper arm, two short lower links arranged side by side, multiple riveted pivots, and a black end stop at one end of the track. Round and elongated fixing openings provide distinct reference points for installation alignment.

The close-up views also show a dark internal track plate with a slotted gold-tone screw and a low stacked profile when the linkage is folded. Before selection, buyers should verify the track length, mounting dimensions, fixing-hole positions, folded stack height, hinge configuration, opening direction, profile connection, and required load target. Sash dimensions, sash weight, and the intended opening angle must be reviewed as system-specific requirements.

For an OEM or ODM enquiry, provide a dimensioned drawing or physical sample, sash and frame profile sections, mounting position, opening direction, required quantity, finish reference, and packaging instructions. CHIER can then review the black end-stop arrangement, pivot geometry, track clearances, and connection layout against the proposed window assembly.
