Use this Flat Surface Adapter to attach either the Precision-Adjust Rotating Pier Adapter (900RPA) or the Hi-Lo Latitude Wedge (900WDG) to a flat plate on your custom made pier or tripod. You can also use it with the Standard Pier Adapter (900SPA) to give a more finished appearance.
The 900 Flat Surface Adapter is precision machined aluminum. It has been polished smooth and then anodized black.
The Flat Surface Adapter bolts onto the flat plate on top of your pier or tripod, then the Pier Adapter or Hi-Lo Latitude Wedge 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.
The bolt circle for attaching the 900 Flat Surface Adapter to your pier is 7.230†in diameter. This is the same size bolt circle as is found on our Standard Pier Adapter (900SPA), so if you are replacing a Standard Pier Adapter with a Rotating Adapter or Wedge, you can use the same holes. The holes for mounting the 900FSA to your flat surface are counter-bored to accept the head of a standard ¼†socket head cap screw (13/32†or 0.406†diameter). This allows the Pier Adapter to sit perfectly in the Flat Surface Adapter. Because installations will vary, we do not provide the four screws for mounting the Flat Surface Adapter to your pier or tripod. Your pier''''s'' top plate should be a minimum of 7.75" in diameter. The 900 Flat Surface Adapter itself is 8.375" in diameter
