Description

Flat Packers in a mixed thickness assortment and 28mm width. Colour-coded polypropylene shim for precision positioning of window and door frames.

The flat, rigid faces distribute load evenly to maintain accurate alignment during installation. Made from moisture-proof, non-corroding polypropylene for long-term stability in timber, uPVC, and aluminium frames.

Chamfer-free edges ensure maximum surface contact beneath screw heads and frame feet, while the non-staining material protects the substrate’s appearance.

Features:

• Colour identification: Mixed colours provide instant recognition of individual thicknesses within the pack.


• Load stability: Rigid polypropylene gives stable support under typical frame screw clamping without crushing, maintaining alignment.


• Moisture and rot resistance: Non-absorbent plastic will not swell, rot or corrode in wet openings or fresh plaster.


• Clean seating: Smooth, burr-free faces help achieve full contact for reliable load spreading beneath frame fixings.


• Stackable use: Uniform geometry allows stacking with other packers to build precise builds without rocking.


• Substrate compatibility: Safe for timber, masonry, concrete and metal frames; electrically non-conductive.


• Size: Mixed thickness × 28mm width – versatile selection for varied gaps and progressive adjustment.
