The Chandler 1010-7003 Manway is a non-code, gasket-in-lid dome design built for vacuum tanks operating under maximum vacuum and low pressure conditions, trusted by top OEM vacuum truck manufacturers. The 5-wingnut latching design is typically used at the rear of the truck but can also be mounted on top of the tank. It features a 20-inch steel lid with a 6-inch steel weld neck, and comes standard with an assembled wingnut and hinge assembly along with a Buna gasket. This manway is commonly used on septic trucks, grease trucks, brine haulers, portable toilet trucks, and wastewater trucks.
