Description

As of July 2012 , the Flat Surface Adapter (formerly part # 1200FSA) has been upgraded to include four additional thru-holes for more secure attachment to a flat plate with the larger 1600GTO and its payload in mind. It also includes "N" and "S" engraving to ensure that the base of your mount will be oriented in the correct direction when it is inserted.

The 1612 Flat Surface Adapter is black-anodized, precision-machined aluminum.

1600GTO

• The base of the 1600GTO slips directly into the 1612FSA. There is no need for an extra pier adapter, as the 1600 incorporates the functionality of the Precision-Rotating Pier Adapter into its base. The extended latitude range of the 1600 also eliminates the need of a polar wedge.

1200 (all versions)
Use this adapter for these applications:

• Interface between the Precision-Adjust Rotating Pier Adapter (1200RPA) and the flat plate on your custom made pier or tripod.
• Attach to the top of your 1200 Hi-Lo Latitude Wedge (1200WDG) if you wish to use the 1200RPA.
• Although the Standard Pier Adapter (1200SPA) can bolt directly onto the flat plate of your pier or tripod, you can use this adapter to give a more finished appearance.

Attach to flat surface
The Flat Surface Adapter bolts onto the flat surface on the top of your pier or tripod. Your pier's top plate should be a minimum of 9.75" in diameter. The 1612FSA itself is 10.345" in diameter. It adds 1.265" to the height of your mount.

The bolt circle for attaching the 1200 Flat Surface Adapter to your pier is 9.230" in diameter. Please refer to the PDF link provided on the diagram to the right for detailed information on attachment preparation.

The holes for mounting the 1612FSA to your flat surface are counter-bored to accept the head of standard ¼" socket head cap screws (13/32" or 0.406" diameter). This allows the 1600 base or 1200 Pier Adapter to sit in the Flat Surface Adapter without interference. Because installations will vary, we do not provide the screws for mounting the Flat Surface Adapter to your pier or tripod.

You may wish to consider purchasing our Flat Pier Plate with Flat Surface Adapter for 1600GTO and all 1200 Mounts (1612FSA-FP) if you are fabricating your own pier and need a flat plate to fit into the top. Some modification may be required to fit your pier I.D.

Attach to 1200 Hi-Lo Latitude Wedge
Match four holes and bolt the 1612FSA in place. Then, your Pier Adapter simply slips in (just as it fits into our pier) and you fasten from the side with the six screws and washers provided with the Pier Adapter for your 1200 mount.

Fasteners included:
¼”-20 x ¾” Socket Head Cap Screws (8)
