Four Wheel Multi-Position Steel Hand Truck. This hand truck is great for uneven surfaces and outdoor work. Small 4" x 1¼" mold-on-rubber swivel casters are located at the back of the cart to stabilize loads and prevent tipping. The back casters will also transform the unit into a horizontal platform truck. The unit will lie back horizontally, the handle will release to a standard position and now the cart is a platform truck. 10" x 3½" pneumatic casters. Ships knockdown. Specs: overall size 23 3/4"W x 22"D x 50"H ; nose plate 16 1/4"W x 12"D; capacity 400lbs.
