6mm Flat Packing. Maximum Flat Thickness.

These 100x28mm red flat shim packers are the thickest in the flat range — the choice when no other single flat packer will bridge the gap. At 6mm, they eliminate the need to stack multiple thinner packers, giving you a cleaner, more stable result with fewer components and less risk of movement over time.

Colour-coded red for instant identification on site, and supplied in a bulk pack of 1000 for large-scale trade projects.
