U Packers – Polypropylene – Precise Alignment

Product Overview

Our Mixed Thickness U Packers come in assorted thicknesses from 1mm to 10mm, perfectly designed for a variety of tasks. Easily slide these packers around existing fixings without removing screws, maintaining accurate datum and line during setup. Each packer is color-coded for quick identification, and the rigid, non-compressible polymer provides a stable bearing under typical frame loads.

The internal comb design ensures a secure grip, resisting movement during tightening and final fixing. Made from non-absorbent and non-staining materials, these U shaped shims support both minor and major adjustments, ensuring a clean and professional installation.

Features & Benefits

• Color Coding: Quick visual confirmation of size in mixed sets and busy sites.

• Non-Compressible Polymer: Maintains level and square under typical frame loads.
• Moisture and Rot Resistance: Suitable for interior and exterior use.
• Clean Edges and Flat Faces: Distributes bearing evenly to protect frame finishes.
• Reusable: Can be repositioned during dry-fit and left in place for final fix.

Applications

• Window and Door Frame Setting: From fine reveal tuning to substantial pack-off.
• Batten and Subframe Alignment: Establishing datum over variable substrates.
• Hardware Seating: Backing light to heavier brackets and plates.
