This is a resin spacer that allows you to fine-tune the gap between the sash frame and the mounting base.
Spacers with a thickness of 0.5 mm are bundled together in groups of 20 and welded together, and can be cut into pieces of the required thickness for use.
By ensuring that the vertical sash frame is properly leveled, it helps prevent wobbling when opening and closing the sash. Size: 27 x 50 mm
Thickness (mm): 0.5 (per sheet)
