English and Metric Post Holders

English and Metric Post Holders secure post-mounted optical components to lab tables and breadboards. A 3-point contact design centers Stainless Steel Optical Mounting Posts within the holder, while engraved thread values make English and metric versions easy to identify. Lengths range from 25.4mm (1") to 152.4mm (6"). An optional magnetic pedestal base allows the post holder to be repositioned on magnetic lab tables without changing the mounted component.
