Anti-corrosive ABS construction and a screw-in cover form a compact inspection hatch. Separate cover and chassis aid straightforward access and maintenance.


Leak-free access - thanks to a rubber O ring

A rubber O ring sits in the cover channel to compress against the chassis when the cover is secured, creating a water-resistant barrier for the opening.

Secure checks during wet conditions reduce the risk of water ingress to bilges and equipment, keeping compartments drier and safer.

Easy installation and service - with separate cover and chassis

Cover and chassis are supplied separately so the cover can be removed without disturbing the mounted base, and the screw-in design is described as non-jamming.

Quick access for wiring or minor repairs makes routine inspections faster, helpful for both DIY owners and professionals.

Corrosion resistance and neat finish - with anti-corrosive ABS material

Moulded from an anti-corrosive ABS compound with a smooth surface finish to resist salt exposure and surface wear over time.

Low-maintenance appearance that stays tidy in marine settings, reducing the need for frequent replacements or refinishing.
