The Schier Safety Manway builds on the Safety Star concept that comes standard on the GB-500 and GB-1000 models. An open manway is a safety concern and every year people fall inside and are injured or worse, killed.  The Safety Star was developed to help protect against accidental entry into the grease interceptor. As the photo shows the pumper hose will still fit inside of the openings and the bright yellow Safety Star can hold 400 lbs. It's also removable but comes with a tether to make sure it doesn't go too far. A security screw can also be used to help with tampering. 

The Safety Manway is designed to be a universal fit for any buried tank. Concrete grease interceptors, oil/sand separators, chemical tanks, solids interceptors,  septic tanks, sanitary sewer access points, storm sewer access points just to name a few.
