Installation planning
- Compare the selected hatch with the existing opening, surrounding mounting surface and six fixing positions.
- Allow room to turn and remove the lid and to reach the compartment below.
- Confirm the cutout, fixing pattern and suitable panel thickness before making a new opening. Contact ROQIFY with your measurements if replacing an existing hatch.

A watertightness or load rating is not specified here. Choose the installation location and sealing method according to the vessel's requirements.
Ask ROQIFY about dimensions and fitment before ordering if your existing opening or mounting arrangement differs.
