This series of miniature post holders features an attached swivel base offering a variety of mounting positions on Mini Breadboard. The post holder contains a spring-loaded frictional element that prevents the post from slipping down into the holder prior to final tightening of the thumbscrew. The bottom of the post holders has a pass-through design that provides for a maximum range of beam heights when assembling an optical system.
