JEGS Bone Creeper is an American made product featuring a body that cradles the user between the wheels only 1.75” above the ground. The rib-reinforced body is molded out of an engineering grade co-polymer that is resistant to common solvents. The ergonomic one-piece design doesn't have any corners or pinch points. Five inch, smooth rolling wheels are positioned outboard to provide a stable working platform that won’t tip or flip. These wheels have specially formulated 1” wide tires that roll easily over all kinds of obstacles, including rough floors, drop cords and air lines. Steel caster frames have a winged design with dual race adjustable ball bearing swivels that are bolted through the creeper body.
