Installation
Clamp-ring sealing: All clamp-ring installations use the foam seals supplied with the windows. If the seal is not pre-applied, fit the supplied foam seal to the exterior frame as directed for the model. Tighten the mounting screws evenly to compress the seal uniformly.
This is a clamp ring window. Plan your location first and confirm the cutout fits between ribs and structure. Cut the opening to the listed cutout size. Set the window in the opening with the seal in place. Install the clamp ring and tighten evenly in a cross pattern until the seal compresses uniformly. Confirm slider movement, latch function, and screen operation before final tightening.
