5mm Flat Packing. Substantial Gaps, Clean Results.

These 100x28mm blue flat shim packers are built for the more demanding end of the flat packer range — a 5mm thickness that handles significant gaps and corrections without the need to stack multiple thinner packers. Whether you're dealing with an uneven substrate, a wide reveal, or a floor with pronounced variation, the 5mm blue delivers a stable, single-piece solution.

Colour-coded blue for instant identification, and supplied in a bulk pack of 1000 for large-scale trade use.
