Astro-Physics 1612FSA-FP Flat Surface Adapter with Flat Pier Plate

Astro-Physics 1612FSA-FP Flat Surface Adapter with Flat Pier Plate for 1600GTO and all 1200 Mounts - For 10" ATS and other non-Astro-Physics piers

If you are ordering a 10" ATS pier for your 1600GTO, you will need to order this adapter to interface the pier post with the base of your mount. You may also consider it if you are fabricating your own pier for either the 1600GTO or any 1200 mount. You do NOT need this adapter for the 10" Astro-Physics Piers.

This item is constructed of two machined aluminum parts bolted together - a thick flat plate and our Flat Surface Adapter for 1600GTO and 1200 Mounts (1612FSA) . Since the bottom of the flat plate is designed to fit into the 10" ATS Piers, the diameter (9.450") is too small to be used in the Astro-Physics 10" Portable Piers. This adapter adds 2.015" to the height of the ATS pier.

The lower flat-plate section of this adapter is also drilled and tapped so that the 119FSA (formerly part # 900FSA) can be attached. This allows the 1100GTO and all 900 mounts to be attached to your 10" pier.




Use with 10" ATS Piers and 1600GTO

The base of the 1612FSA-FP has already been machined per the specifications provided by ATS to fit into their piers without further modification. The 1600GTO will fit directly into the top portion of the 1612FSA-FP.
Use for Other Piers and 1600GTO

Machine the bottom portion of this plate to fit the I.D. of your pier. The base of the 1600GTO will fit directly into the top portion of the 1612FSA-FP.
The Particle Wave Monolith will receive this adapter directly, provided that it has the reported 9.50" inner diameter specification.
Use for Other Piers and 1200 Mounts

Machine the bottom portion of this plate to fit the I.D. of your pier. Please refer to the diagram to determine if your pier is suitable.
These adapters for the 1200GTO will fit into the top portion: Precision-Adjust Rotating Pier Adapter (1200RPA), Standard Pier Adapter (1200SPA), or 1200 Hi-Lo Latitude Wedge (1200WDG or 1200WDGA) .
