Bigger Wheels for a Better Ride. Our popular plastic creepers are now available with larger, 4" pop-in urethane wheels. The larger wheels provide a much smoother ride on cracked or uneven floor surfaces, over floor debris and under heavy loads. Also rolls better on regular floor surfaces. The creeper body is the same as our low profile plastic creeper models. Available in Red (LIS-92032), Yellow (LIS-93032) and Blue (LIS-94032).
