This Nutting Truck Platform is ergonomic and reduces the repetitive motion of moving mail totes off the Nutting Truck can cause strain to the back. This ABS platform raises the totes to a more comfortable level to reduce bending. The platform attaches to three steel support bars with self-tapping screws. Notches on the support bars fit over the rail's horizontal crossbars. (Rails must be turned so crossbars face inside) and place the platform on the crossbar at the desired height. ABS Plastic Platform is more flexible than other plastics and can support the weight of many mail totes without cracking. The platform features three steel bars, two piece ABS platform, and self-tapping screws.
