Colson Antimicrobial Expanding Stem Caster, 4" SS04AMP125SWXRN2G

These expanding stem casters are made from stainless steel and resist corrosion when exposed to water and chemicals. - The casters' wheels are impregnated with an antimicrobial compound that prevents microbes from growing on the wheels and damaging them or causing odors. - The casters have thread guards that stop dirt and debris from getting into the casters and damaging them. - The casters' wheels have precision ball bearings that provide quiet rolling, and the casters have double ball swivel bearings for smooth swiveling. -These casters are used on carts and equipment in locations where noise must be minimized and high standards of cleanliness must be maintained, such as medical, laboratory, pharmaceutical, and food-service facilities. - Expanding stem casters install into structural tubing, and they don't need to be secured with bolts or pins. - Each caster has a knurled nut that is tightened to expand the rubber sleeve on the caster's stem until it is large enough to firmly grip the inside of the tubing. - These versatile casters can be installed in range of round tubes with different internal diameters. - They can be mounted to carts, racks, stands, cabinets, and furniture made from structural tubing to allow these items to roll, which reduces effort when moving or repositioning the items.
