VMS Stainless Steel Inspection Hatches
VMS manufactures two sizes of Stainless Steel Inspection Hatches for use on fuel tanks in yachts and boats.
The inspection plate and the retaining flange are made from 4mm 304 grade stainless steel plate with all edges smoothed for safe use. Using the instructions listed below, a cut-out is made in the desired location, and an inner retaining flange then held in place inside the fuel tank, while the cork rubber gasket is laid on top of the fuel tank and the inspection hatch finally bolted through to the retaining flanges pre-threaded holes. Job done!
