Thorlabs offers our Ø25 mm Post Spacers in a compact, comprehensive kit. These spacers are designed for achieving "in between" heights of our Ø1" (Ø25 mm) Posts without compromising structural rigidity. The center Ø1/4" (M6) clearance hole allows threaded studs to pass through to the mating tap of the components on either side of the spacer. Achieving, for example, a total post height of 8.2" is as simple as inserting one RS5M spacer (0.2" thickness) in between two RS4 posts (4" length).
