The B&B Rolling Crate Cart is a nice addition to the B&B cart line and works on the same modular platform. This simple, yet effective, four sided material handling cart is a great storage and transport cart for pipe fabrication. It handles a 1,500 lbs. weight capacity and yet still fits through a 36″ door frame common on job-sites. Six 6″ steel wheels are standard and shipped assembled with the rolling crate cart.
