Base plates are commonly used for positioning and fastening our PSH-series of Post Holders
to optical tables. Posts and post holders are attached to the base plates via M6 or 1/4-20 cap screws placed through the bottom-located counterbores.
This radial slotted mounting base plate is designed to be a stable, rotatable method of mounting a post or post holder to the optical table. The mounting base plate has 3 bottom located counterbored clearance holes for M6 or 1/4-20 cap head screws. Likewise, a machined relief cut has been added to the base mounting plate to assure flat, stable mounting to a variety of surfaces including breadboards and optical tables. The two 90-degree radial clearance slots allow easy mounting to either an imperial or metric breadboard. This post holder base plate is compatible with imperial and metric tables, posts, and post holders.
