Opening:
Turn the clamps a quarter turn outwards and pull on the window to open it. The window
will remain open in any position because of its clamp hinges.

Check that the clamps are in the ‘open’ position. Push the window closed and turn the
clamps a quarter turn inward.
Fitting
The porthole can be fitted in a surface with a minimum thickness of 3 mm. and a maximum
thickness of 11 mm.
Draw the hole to be cut out using the porthole frame, for the main dimensions, see page

Cut the hole in the ship by sawing in polyester, aluminium or wood, or by acetylene cutting
for steel.
Remove all burrs carefully and smooth the edges.
Position the porthole in the hole and mark the fixing holes for frame and backplate, see
Drawing 1. Drill the holes and remove any burrs.
Apply a sufficient amount of sealant to ensure a good seal, see Drawing 1 - (2).
Position the hatch in the hole.
Fixing Screws:
Use M4 screws with plain washers and cap nuts, see Drawing 1 - (2).
Fit nuts and bolts or screws and tighten securely.
Maintenance
