Product Overview
Flat Packers in a mixed thickness assortment and 32mm 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 & Benefits
- 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 × 32mm width - versatile selection for varied gaps and progressive adjustment.
Applications
- Window frame setting: Establish plumb, level and square before fixing.
- Door frame installation: Shim hinge and strike sides for precise reveals.
- Partitioning and stud work: Pack track and studs to true lines prior to boarding.
- Joinery and cabinetry: Fine adjustment under sills, casings and carcasses.
- Cladding and battening: Space battens off substrates for drainage paths.
Installation Guidance
- Select thickness: Choose packers to match the required gap and build by stacking if needed.
- Place for support: Position directly under frame load points and at fixings to spread pressure.
- Fix without distortion: Tighten screws to secure while avoiding excessive compression that could deflect the frame.
- Verify alignment: Check level, plumb and diagonals; adjust with additional packers as required.
- Trim if necessary: Flush‑cut any protruding packer edges after final fixing.
Compliance & Performance
- Material specification: Colour‑coded polypropylene (PP), non‑staining and corrosion‑free for building substrates.
- Service suitability: Intended as non‑structural spacers for alignment and load spreading under typical frame fixings.
- Environmental durability: Resistant to moisture and common site contaminants; suitable for interior and sheltered exterior use.
- Important note: Not a substitute for structural bearing or load‑rated shims; verify suitability with the project specification.
