PACKSHIM6MM Plastic packing shims are the easiest, fastest and most economical way to level or align, battens, frames, kitchen units, panels and floors or even DIY jobs. They are very cost effective and are more accurate than hand cut hardwood or plywood. Each packer is colour coded for ease of size identification. Packing shims are manufactured from high quality plastic and are resistant to weather changes and are waterproof. Packing shims are tapered at the front and back to assist stacking and also have flexible retainers to prevent the packing shims falling off. • 40mm x 45mm •
