Packer

In trades, "packers" (also called shims or spacers) are small, often colour-coded plastic or metal pieces used for levelling and support. Carpenters & Joiners: Used to level kitchen cabinets, align timber decking, or fit window and door frames. Concreters: Heavy-duty packers support precast concrete panels and distribute loads evenly. Stonemasons & Tilers: Used to prevent heavy wall cladding or tiles from sagging during installation. Home DIYers: "Weekend warriors" use them for home maintenance tasks like levelling furniture or "wonky toilets".
