I have a 1200, and use the SPA Standard Pier Adapter

<> to mount it on my concrete pier.

The pier is 12" diameter, but reduces to 10" at the top, and the SPA

attaches to 5/8" threaded steel rods embedded in that.


This link: <>

illustrates and describes what I did.


One note: The cap screws attaching the SPA to the rods are 1/4"-20. I

drilled a #11 hole in one end of each rod, then tapped that for 1/4"-20.

This hole should be coaxial with the rod, so a vise on a drill press is

helpful. I'm fortunate to have a mini-lathe, so I chucked the rod in the

lathe, and easily drilled coaxial holes.


My SPA is circa 2005, and I don't know if the current one is the same.
