Made with grey rubber for strength and durability, this Feltac caster is a great choice for multi-purpose applications. The 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 protective metal thread guards. The mounting plate is 2 9/16" x 2 9/16" (65 x 65 mm), making it easy to secure and install on flat surfaces. The caster is 4 1/6" (103 mm) in height, has a 3" (75 mm) wheel diameter and has a load capacity of 132 lbs (60 kg).
