They can be easily slid around existing fixings without removing screws, helping to maintain accurate datum and line during set-out.\u003cbr\u003e\u003cbr\u003eEach packer is colour-coded for quick on-site identification. The rigid, non-compressible polymer provides a stable bearing under typical frame loads, while the internal comb design ensures a secure grip that resists movement during tightening and final fixing.\u003cbr\u003e\u003cbr\u003eThe material is non-absorbent and non-staining, ensuring a clean, professional installation against both frames and substrates. These U shaped shims reduce stacks and speeds set-out on variable bases.\u003cbr\u003e\u003cbr\u003eUsed singly for confident pack-off or combined with finer sizes to tune level and reveal, they maintain consistent plane across the bearing face to protect frame profiles and finishes.\u003cbr\u003e\u003cbr\u003eThe 10mm thickness is suited to extra-large gaps or specialist fitting where a significant correction or stand-off is required.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch2\u003eFeatures \u0026amp;
