Trade-Grade Frame Packers (1–6 mm +)
Frame packers provide stable, non-compressible support for door and window frame installations. Placed behind fixing points, they keep frames true, prevent twist, and ensure even load distribution across the structure.
Our range includes Type A–H profiles covering different widths and configurations, all following industry colour coding for quick identification. Suitable for uPVC, aluminium, and timber systems.
Choose single-size or mixed trade packs for larger projects. All frame packers are stocked in the UK with next-day delivery and VAT invoices included.

Frame Packers – FAQs
Frame packers are rigid shims used behind fixing points to align and support door and window frames. They prevent distortion, ensure even load distribution, and keep frames square during installation.
Each type has a different width and footprint for specific frame systems and load conditions. For example, Type A suits narrow fixing points, Type B offers wider load support, and Type H fits deep aluminium sections. See the guide above for a full breakdown.
Most installations use 1–6 mm packers. Choose the smallest thickness that achieves a level, square frame without stressing the fixings or substrate.
