- Extension Post Used to Extend the Height of Our RS Series Ø1" Pillar Posts
- 1/4"-20 Tapped Hole on Both Ends
- 3/16" Balldriver Hole Provided for Extra Leverage During Tightening
- Large-Diameter Relief Cut on Top and Bottom for Additional Mounting Stability
This 1" long Pillar Post is ideal for enhancing our fixed height riser supports. It contains a 1/4"-20 tapped hole in both ends for direct mounting to an optical table or standard base and an optical mount, and it is machined from nonmagnetic 303 stainless steel.
An AE8E25E adapter, which has external 1/4"-20 threading and internal 8-32 threading, is also included. The adapter can be used with an 8-32 setscrew to attach many of Thorlabs' imperial optomechanical parts to a Ø1" imperial pillar post. In principle, the adapter can also be used to connect two Pillar Posts, but a solid 1/4"-20 setscrew, which is included in our HW-KIT4 hardware kit, is a more stable choice for this.
