Built with high-density polyethylene resin, and steel legs and frame. These are HEAVY-DUTY, resin tables (not Lite Duty, like common blow mold tables). Rhinos have been tested by SGS Labs, and rated at 2400 lbs. capacity. Weather resistant and low maintenance, Rhinos never need sanding or refinishing. Rounded corners help to avoid damage. This lightweight table is easy to set up and take down. Gravity locking, wishbone legs are standard, and the tops have a ¾ inch edge to allow for skirting.
