The Adjustable-Height Swivel Seat Creeper, No. 42304A, from Williams allows technicians to sit at heights between 17” and 22” on a comfortable, square-seat design. The creeper features four 2-1/2” diameter hooded casters that shield technicians' clothing from dirt and grease. In addition, the steel-tube frame supports the seat’s cylinder for strength, and a bottom pan can be used for storage of tools and small parts.
