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.
