Designed for durability and strength, this heavy-duty Madico caster is a great choice for use in even demanding environments. The smooth non-marking tread and two independent rows of freely rolling hardened ball bearings ensure it operates smoothly and easily over hardwood, tile, linoleum, carpet, ceramic, concrete, and steel surfaces. The caster features a rigid design, has a zinc finish for corrosion resistance, and the thermoplastic rubber resists chemicals, caustics, oils and wear. The mounting plate is 2 15/16" x 4 1/8" (74 x 105 mm), making it easy to secure and install on flat surfaces. The caster is 5" (126 mm) in height, has a 4" (102 mm) wheel diameter and has a high-load capacity of 247 lbs (112 kg).
