Ø25.4mm (1in) stainless steel mounting posts are used in applications where rigidity and stability are most critical. Mounting critical components on these fixed height non­magnetic, stainless steel posts over Ø12.7mm (1/2in) posts can provide a more stable starting point for an optical setup. These posts are tapped with a M6 at one end to mount directly to the optical table or base and an M4 on the other end to directly mount component holders like mirror mounts and fixed optic mounts.

The post also has a Ø6.4mm hole through the middle to allow a ball driver or L­wrench 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.
