These plastic leveling shims provide a simple way to stabilize toilets, doors, windows, sheds, and furniture. Each wedge style shim can be stacked, overlapped, or trimmed to help close gaps and support heavy fixtures without shifting. The durable plastic construction resists moisture and will not compress like some wood shims, making them suitable for long term use in bathrooms, basements, and outdoor structures. Their compact size and tapered design make them easy to position in tight spaces during installation or repair work, helping you correct minor unevenness in floors or framing. Keep a 12 pack on hand for general leveling tasks around the home, workshop, or jobsite.
