This kit contains four machined and black anodized Pier Adapter Knobs and 5/16 " ID x 1.5" OD flat washers. If you do not purchase one of our pier adapters shown above, for instance, if you purchase the Monolith Pier from Particle Wave Technologies, you will need these knobs to attach your 1200 mount to the Monolith.
The kit can also be purchased as spares if you lose or damage the knobs that came with your Standard Pier Adapter (1200SPA) or Precision-Adjust Rotating Pier Adapter (1200RPA). Please note, a complete set is included with your pier adapter when you purchase it.
Fits all 1200 mount models (HDA, QMD, SMD and GTO) that have been produced.
