Flat Packers – Polypropylene – Framing Precision

Product Overview

These industrial-grade flat packers feature a 1mm thickness and a 28mm width, designed for precision positioning of window and door frames. The color-coded polypropylene shim ensures quick size recognition, reducing selection errors on site.

With flat, rigid faces, these packers distribute load evenly to maintain accurate alignment during installation. Made from moisture-proof, non-corroding polypropylene, they offer long-term stability in timber, uPVC, and aluminum frames.

Features & Benefits

• Color Identification: Green body for fast size recognition and reduced selection errors.
• Load Stability: Rigid polypropylene provides stable support without crushing.
• Moisture and Rot Resistance: Non-absorbent plastic prevents swelling, rot, or corrosion.
• Clean Seating: Smooth, burr-free faces ensure reliable load spreading.
• Stackable Use: Uniform geometry allows stacking for precise builds.
• Substrate Compatibility: Safe for timber, masonry, concrete, and metal frames; electrically non-conductive.

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 stack as 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.
• Verify Alignment: Check level, plumb, and diagonals; adjust with additional packers as needed.
• Trim if Necessary: Flush-cut any protruding packer edges after final fixing.
