Our covers are all custom made, so nearly any size well can be covered. Our covers are constructed of a tough translucent fiberglass. The frosted appearance assures privacy, yet allows 95% of the daylight through. We also use sturdy, non-rusting aluminum cross braces on all escape (egress) covers. All covers are designed to support at least 500 lbs. Our patented back rail design allows for special needs where the window extends above the level of the well.
