Great Weight Capacity: Unlike common self adhesive mini caster wheels, our new adhesive wheels feature a large 25mm (1 inch) diameter steel ball in the ABS bracket for effortless and smooth rolling. Each wheel supports 28 pounds, with 4 wheels having a total load capacity of 112 pounds, and 8 wheels supporting up to 224 pounds. Premium Material: Our upgraded casters are constructed with quality metal and thick ABS material, ensuring sturdiness and durability. No more worries about heavy furniture being difficult to move during floor cleaning. These 360 swiveling casters make it easy to move and rotate furniture and appliances freely. Product Design: The compact design of our caster rollers allows for easy installation on the bottom of small furniture and appliances without affecting aesthetics. Versatile for mounting on feet or legs of items like coffee tables, cabinets, bookshelves, nightstands, planters, and more. Note: Suitable only for smooth, hard surfaces and may leave marks on wooden floors. Easy to Install: The casters are extremely easy to install, simply stick the tape to the casters and attach to the furniture. Installation diagrams in the product manual provide additional guidance. Warm Tips: To avoid floor scratches, do not use with heavy furniture (over 44 lbs.) on white stone or tile floors.
