This ergonomically designed 6 bushel truck eliminates stooping and bending and makes for efficient loading and unloading. The heavy-duty poly tub is rugged and easily cleaned. Internal dimensions are 28 1/2"L x 18 1/2"W x 21"D. The nominal wall thickness of the tub is .225" allowing for the toughest jobs. The tub is attached to our heavy-duty zinc plated tubular base with stainless steel hardware and rubber washers to seal the tub and make it leak proof. This unit is equipped with R&B's proprietary 5" Clean Wheel System - the only caster that prevents lint and thread pick up. The detachable tubular base allows us to ship this unit knocked-down for a great freight value.
