unique cantilever design allows for oversized packages to fit conveniently
on the bottom shelf without restricting access to the packages. Eliminate
the need to move around a clumsy ladder and push a cart while trying to
stock or un-stock shelves. The step ladders are spring loaded to hold the
cart securely in place while a person is standing on the ladder. Two rigid
and two swivel 4" x 1½" mold-on-rubber casters standard. Total uniform
capacity is 440 lbs. per cart, uniformly loaded.
