28" wide stationary base plate is designed to be sealed permanently to the floor. The round upper cover seals to the base with bolts and rubber gasket to make air tight. Installed in the cover are a 5 port cord seal, 3" threaded flange and a adjustable flange in the top of the cover to accommodate pipes from 2" to 1-1/4".

This cover also has 6 flat areas on the side of the base to allow for side discharges from the sump. This will allow these pipes to remain stationary when the pump needs to be serviced.
Note: For large basements and or high radon levels, 4" pipe should be used for maximum radon reduction. A hole saw can be used to modify this cover if needed.
