Compact Base Plate

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 post holder 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 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. A 1/4-20 clearance slot allows easy mounting to the optical table or breadboard. This post holder base plate is compatible with imperial and metric tables, posts, and post holders
