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 1/4"-20 (M6) cap screws placed through the bottom-located counterbores.
This slotted mounting base plate is designed to be a compact method of mounting a post or post holder to the optical table. The mounting base plate has a single bottom located counterbored clearance hole for 1/4-20 or M6 cap head screw. 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. 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
