If you plan to install your 3600GTO onto a pier with a flat plate, we suggest our flat surface adapter. The 3600GTO fits into the ID of the adapter; eight bolts hold the mount in place. This adapter is machined from a solid plate and is ribbed in the base for strength and reduced weight. It is 12" OD, 1 7/8" tall and weighs 5.75 lbs.
- Eight (8) bolts on a 10.788" diameter bolt circle
- Three (3) bolts spaced 4.25" from the center and one (1) bolt 3.125" from the center. This spacing allows you to attach the adapter to the 1200 Standard Pier Adapter (1200SPA), which allows it to be used in a 10" diameter pier. We used this option before our pier was completed.
- Center bolt hole to use if you chose.
