Plastic Frame Packers

Durable Support Shims for Accurate Door & Window Frame Installation (1–6 mm +)

Frame packers are designed to sit behind fixing points and provide firm, non-compressible backing during the installation of window and door frames. By supporting the frame evenly, they help prevent twist, maintain squareness, and ensure that fixings distribute load correctly across the structure.

All frame packers are held in UK stock, dispatched quickly, and supplied with VAT invoices as standard.
