They easily slide around existing fixings without the need to remove screws, ensuring accurate datum and line during set-out. Each packer is color-coded for quick on-site identification, providing a stable bearing under typical frame loads. The internal comb design ensures a secure grip to resist movement during tightening and final fixing.\u003c\/p\u003e\u003cp\u003eThe non-absorbent, non-staining material guarantees a clean, professional installation against both frames and substrates. U-shaped shims reduce stack heights and speed up set-out on variable bases.
