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 9/16" x 3 5/8" (65 x 92 mm), making it easy to secure and install on flat surfaces. The caster is 3 7/8" (99 mm) in height, has a 3" (76 mm) wheel diameter and has a high-load capacity of 176 lbs (80 kg).
