Water-tight Retrofit SNAP-LOCK submersible cover
This is our SNAP-LOCK submersible tank sump cover kitted for you as a retrofit. The tank sump reducer must be made of fiberglass and you must laminate the retrofit reducer onto the existing one. This is the water-tight cover you need underneath a seal-less manway cover. Using our reducer size selection chart, match one to your existing sump reducers , then secure and laminate them in place. Drop the SNAP on, step on it to engage the seal, turn the cam locks and walk away. Check out the SNAP-LOCK link below for more info and a video.
