Easily inspect your sump pump with this 3/16" thick ABS sump cover that has an installed screw off inspection port. Port is installed about 2" from the edge of the cover. The cover can be cut to fit the size of the sump crock.
Inspection port screws off for easy access and the transparent center plate permits observation without the necessity of removing the cover.
This 23 3/4" sump cover has a slight imperfection along one edge causing it to measure 23 1/2" at that point.
