✅Glazing packers plastic engineered to support glass in aluminium, wood or PVC framework. These blue polymer strips slot beneath panels to prevent direct contact with the profile. Suitable for windows, doors, furniture, shower enclosures, roofs or seating assemblies. ✅ These plastic window shims protect panes from screw-induced fractures by distributing pressure evenly. Their insulating nature reduces vibrations while accommodating thermal expansion and contraction. Simply bend for corner alignment or snap into 3 segments for targeted levelling. ✅ Our window glazing spacers feature high-grade polypropylene construction for robust performance, precision and lasting resilience. Each rectangular shim divides into three pieces to maximise coverage, and a non-slip base keeps every packer firmly in place, even when exposed to moisture. ✅ Product Information Colour: Blue Material: PP Thickness: 2 mm Length: 100 mm Width: 20 mm Also known as window glazing blocks, plastic leveling shims or window fitting spacers for precise installation. ✅ [IMPORTANT] - 100% SATISFACTION - If you have any issues with our product, please contact us for assistance.
