Service Caster #20 Series 1/2 inch threaded stem Grade 316 stainless steel swivel casters with a 4 inch solid blue polyurethane wheel and Total Lock brake. These casters are ideal for light and medium duty material handling requiring regular wash down or in wet areas. Total Lock brake solidly locks both the swivel and wheel, providing an exceptionally sturdy base when engaged. All stainless steel components are resistant to water, steam, cleaning agents, corrosive agents, and other rust causing agents.
The polyurethane wheel performs well on most surfaces, and excels on hard surfaces like concrete, tile, and wood. They will not mark or mar floor surfaces.
