Ø1" stainless steel extensions posts are used in applications where rigidity and stability are most critical.Typical applications include supporting small breadboards and creating superstructures over the optical table.  The PTX series 1 inch diameter extension posts are also often stacked with our PTA series Ø1" posts to create custom lengths.

These nonmagnetic, stainless steel posts are tapped with a 1/4­-20 on both sides.  The post also has a Ø1/4" hole through the middle to allow a ball driver or L-­wrench to be inserted providing extra leverage when tightening or loosening the post. A relief cut has been provided on both ends to ensure proper seating.
