Stainless Steel 12.7-mm Post Holders With Pedestal Base

The PHX series 1/2-in. post holders are made from stainless steel and mount with pedestal-style bases. The body, base, and knob are all made from passivated 300-series stainless steel, providing additional stiffness and lower thermal expansion compared to aluminum. Additionally, the stainless steel makes them suitable for applications in UV wavelengths. The pedestal base has industry-standard dimensions making it compatible with all standard clamping forks. The inner diameter is sized for standard 12.7-mm (1/2-in.) posts and provides stable, 3-point kinematic clamping. The PHX post holders also feature an additional threaded clamp-knob hole for better adjustment accessibility when large platforms are post mounted.   If one of our many catalog post holders does not meet your requirements, send us a request for a version
