DESIGN CONCEPT: Traditional casters pose a challenge for narrow furniture legs. L-shaped furniture caster is specially designed for thin and rectangular furniture legs, optimizing space and improving convenience in your daily life. DURABLE AND STURDY: The L-shaped mounting plate of the swivel caster with brake is reinforced to minimize bending after prolonged use of 50mm casters. Each caster loads up to 35KG, with 115KG for a set of 4 in total. In addition, treated with chrome plating, the L-shaped bracket is corrosion-resistant and ensures durability. ROLL WITH EASE: Connecting the mounting plate and 50mm wheels, double ball bearings help make the item rotate smoothly and seamlessly at 360 degrees, ideal for small tables, flower stands, flower shelves, toy boxes, low bookshelves, baby beds etc. FLOOR FRIENDLY: The TPR material used for the tread of the small caster is environmentally friendly and recyclable, providing excellent resilience. It operates quietly, avoiding scratches and marks on all floors such as ceramic tiles, carpets and hardwood floors. EFFORTLESS BRAKING FUNCTION: The 4-pack 50mm tray casters include 2 small furniture wheels without brakes and 2 wheels with brakes. Press the brake to prevent the furniture caster from rolling easily, and lift the brake to make the swivel wheel slide again.
