How to determine the correct size to order:

When determining the size of cover to order for your well, we recommend that you measure the widest points of your well (length & projection) and then order a cover that will be slightly smaller than those dimensions.

 If you want maximum coverage of your concrete blocks or wood timbers, we recommend not going all the way to the outside edges, but about 1" away.  This would mean to subtract 2" from your length measurement and subtract 1" from your projection measurement.    If your well walls are only 4" wide or smaller, we recommend that you go with the maximum size possible.     *email us a photo and we'll work with you to determine the correct size needed.

If the crawl door access sticks above the top edge of your well, the rear of the cover has to go above this opening by 1-1/2". So this determines how much of a slope you will need.

If the crawl door access is below the top edge of your well, we recommend staying with a 6" or under slope as this will help reduce the shipping charges.
