U Packer Mixed Bag (70/Box)

U Packers Mixed Bag of assorted thicknesses from 1mm to 10mm. They can be easily slid around existing fixings without removing screws, helping to maintain accurate datum and line during set-out.Each 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.The material is non-absorbent and non-staining, ensuring a clean, professional installation against both frames and substrates. These U shaped shims support staged builds from hairline corrections to substantial pack-off. Used 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.Mixed thicknesses suited to first-fix and finishing across varied tasks.
