This cart has all the great features of a 72L but includes a “snap-on” cargo security net added over the opening to hold the contents of the cart firmly in place during transport. The lower, wider cutout opening in the cart helps make loading and unloading easier. The Secure Net covers the wider opening of the cart to keep contents safely contained. The 72N is made of chemical resistant, waterproof polyethylene and comes with a powder-coated steel base and industrial strength casters. It is stronger and lighter since it is made of High-Density Polyethylene (HDPE) compared to Linear Low-Density Polyethylene (LLDPE) and has a metal-free interior to avoid snags and tears.
