Pre-82 Lens Installations
|In 1982 we made a change to the frame that required a
to the lens. We can still provide lenses for any year port.
The top lens hinge is manufactured after 1982. The outer posts measure .31 inches and the center post measures .25 inches.
The bottom hinge was manufactured up to 1982. All three posts measure .26 inches.
In most pre-82 installations, you may have a wing nut and washers. There may also be webbing to the outside of the hinge at a 45 degree angle.

A note on Backup RingsThe backup ring is only used if you do not have a screen in the port. We install the backup ring when we ship the ports to the OEM’s to help them install the port. It provides backing for the gasket so the lens seals properly. They should remove the backup ring and install the screen. If you have both in, please discard the backing ring.
Lens order part number LNZ-*** and specify
color. Lens colors are Clear, Smoked (green tint). If the production
date of your boat is pre 1982, order the Pre-82 lens. Each
