I have the 4 sections that make up the base walls(all new repo) and looking them over looking at my pump and pics on the net. I see the covers are not ment to go on the same.
On my pump all panels fit on the Inside of top and bottom rings
The repo parts the extension s fit on inside and the doors (one with hole one without) fit on the outside of the ring
Have any of you used these parts with your original top/ bottom rings?
How was the fit?
Gap between doors and extensions?
I have not looked Inside mine yet. But are the extensions and doors. 2 different heights? |
