Made of 12-guage steel with molded foam cushioning, the low-sling Batwing Ergonomic Creeper provides body support to prevent fatigue and injury when one is working under agricultural equipment and trucks. Only 8 inches off the ground, its back portion is raised/lowered (up to 90 degrees) by a gas spring that's controlled by the user while on the creeper. The rear two of the three locking ball-bearing castors are located at the end of each batwing to ensure maximum stability. Available options include extra wide profile seat, castor guards, and attachable tool boxes.
