20piece set of composite plastic shims for leveling and stabilizing furniture. Designed to fit under legs or corners of bookcases, tables, sofas, cabinets and shelves so furniture sits steady on uneven floors. Key benefits Eliminate wobble and rocking: the angled, inclined trapezoid shape creates a tight shim between floor and furniture leg to stop movement. Precise height adjustment: stackable design lets you add or remove shims for small, accurate changes in level. Durable support: made from longlasting plastic that can withstand heavy loads and provide reliable support for cabinets, shelves and seating. Discreet finish: included colors (black, white and brown) blend with most furniture and reduce the need for visible hardware. Features and function Pack of 20 composite shims for multiple uses around the home, office or commercial spaces. Inclined trapezoid profile and textured surface increase contact and resist slipping on both floors and furniture legs. Breakapart sections allow you to trim the shim length for narrower gaps without visible screws or wedges. Simple to use: insert under the furniture leg, stack as needed, or snap sections off for a precise fit. Practical uses (examples) Level a tall bookcase on an older hardwood floor to prevent tipping and protect items inside. Stop a sofa or armchair from rocking on tile or uneven concrete by inserting shims under problem legs. Finetune kitchen cabinet doors or stabilize a freestanding shelf unit after installation. Compatibility and performance Works with most furniture types and floor surfaces; the textured, angled design improves grip and reduces slip. Built to support heavy loads while maintaining form—keeps cabinets and shelving stable without shifting. Helps maintain a clean, neat appearance by eliminating visible shims or hardware. How to install Slide a shim under the low furniture leg until the piece is level. Stack additional shims for more height or snap off sections to fit tight spaces. Check level and trim or add shims as needed for a snug, nonslip fit. What you get 20 composite plastic shims in black, white and brown, ready for immediate use in homes, offices or commercial settings.
