1.PREMIUM FURNITURE LEVELING FEET: Whether you are purchasing our leveling feet for your furniture or woodworking project, you will find our quality and craftsmanship to be the most attractive in the industry. Constructed of galvanized steel with black PP base, ensuring the furniture levelers are durable, even under heavy loads, supporting over 200 pounds per product. 2.ADJUSTABLE FEET FOR FURNITURE: Importantly, the 1/4' levelers have the ability to adjust individual feet for objects that have uneven legs or sit on a uneven floor. Whether it's furniture or a home DIY project, the leveler height can be adjusted as needed from 1/3″ (8.5mm) to 3/4″ (19mm). 3.MULTIFUNCTIONAL FURNITURE LEVELERS: These table leveling feet prevent wobbling and provide stability and peace of mind; reduce noise; protect floors from scratches; raised furniture feet for easy cleaning from underneath. 4.EASY TO INSTALL: Set with 16 levelers and T-nuts. Inch coarse thread, 1/4'-20 UNC, fits most American made furniture. For furniture legs with 1/4' thread, screw in leveler to adjust. Otherwise pre-drill a 1/3' hole and insert a T-nut, then screw in and adjust (recommend 1/3' or 5/16' drill bit).
