It attaches and opens with the screw-type lifters that were original equipment on the trailer. The lifters are not included. You will receive the Lexan cover only.
Take a look at the MORE PHOTOS button to see how it attaches to your hardware and trailer. We do not sell the gasket, and we now recommend a 1/2" thick hardware store gasket attached to the top rim of your opening rather than on the cover.
NOTE: Because our covers are made of translucent white Lexan, they let more light into your trailer than the original fiberglass versions.
