This round inspection cover with screw closure provides access to inspection openings on or in a vessel. The variant has a clear opening of Ø 102 mm, an external diameter of 147 mm, and a grey surface in RAL 7042.
The cover is screwed on and off the round flange. The design allows the inspection access to be fully opened, while a rubber O-ring ensures a watertight seal when the cover is closed correctly.
The inspection cover is made of polypropylene. The flange has mounting holes around the circumference for fastening, but the required cutout dimension, screw hole diameter, and number of mounting screws are not specified. The stated opening of Ø 102 mm is the clear access opening and must not be used as the cutout dimension.
The product is CE type-approved on the basis of UNI EN ISO 12216:2004 and type-tested in accordance with Directive 2013/53/EU on recreational craft.
