Product Information

Lewmar Atlantic Portlight Features

Anodised Extruded Alloy Frame
Portlight inner and outer frames are made from aluminium extrusion, deep anodised for maximum corrosion resistance.

Quick Action Handles
Portlight handles apply the correct pressure evenly onto the seal in the closed position. Portlight handles are unable to vibrate open when in the closed position.

Water Drainage
The portlight outside frame is designed to allow water to drain away even when mounted on an angled coachroof side preventing water entering the boat when opening the portlight.

Friction Hinges
Lewmar's revolutionary hinges provide a choice of open positions with no knobs, stays or straps. Hinges and other moving parts are corrosion free.

The flyscreen is made from nylon mesh with a moulded frame which clips onto the portlight outer frame. Flyscreen can be left in position when the window is closed. Supplied as standard.
