This low profile hatch cover made from 5mm aluminium tread plate is built to take the punishment. Gas stays make it easier to lift the lids and ensure they remain safely open while in use. Other features include odour containing seals, Securomesh hinged safety screens, heavy duty greasable aluminium hinges and recessed 16mm stainless steel cap screws for locking hatch lid down. Our unique ten4 attachment zed section bolts easily to the foundation pad to prevent access and eliminate theft.
