This flush-mounted polypropylene inspection hatch with bayonet lock is a round, black hatch that provides access to a space or installation area behind it. The outer diameter is 204 mm, and the inner diameter is 155 mm.
The hatch has a rotating bayonet lock, which is used to open and close the cover. The design is mounted completely flush with the surface, so the lid does not create a protrusion.
The lid covers the mounting screws when the hatch is closed. This provides a flush and uniform finish where the fasteners are not visible. The hatch is made of polypropylene and finished in black.
The specified inner diameter of 155 mm describes the hatch's inner opening. No separate cutout dimension is specified, so the mounting opening should be checked against the product itself before installation.
