The ProCart is a versatile, time-saving plastic utility cart engineered to adapt to all the ways – and all the places – you work. Side gates on both the upper and lower shelves flip down to convert this cart from a box-top to a flat-top. Built for years of rugged use, the ProCart is made of high-density polyethylene structural foam. The panels are dent-resistant, rust-proof and never need painting. Even under its 400-lb. maximum payload, the ProCart easily maneuvers around tight corners and through narrow aisles. Each shelf can hold 200 lbs. Use the optional rail kits to hang plastic storage bins or parts cabinets under the top shelf. Assembly is required.
