Frames are 304 stainless steel to resist rust. Wheels have a soft rubber tread for shock resistance with a hard polypropylene core for strength. Use them on smooth or rough surfaces. Flanged-sleeve wheel bearings prevent wear to the wheel bore but don't roll as easily as other bearings. Double-ball swivel bearings provide the smoothest swiveling and are shielded to protect from dust and debris.

Casters with total lock brake the wheel and lock the swivel with one press of the foot pedal.
