TECHSPEC® Right Angle Post Clamps are basic building blocks for optical systems. This post clamp is used to mount two of our 0.5" stainless steel posts at 90° from each other. The posts are locked in place with two ¼-20 thumbscrews. The heavy-duty design provides a stable, secure fit for tightly spaced systems. TECHSPEC Right Angle Post Clamps are constructed of anodized aluminum. Fixed clamp, fixed clamp kit, or rotatable clamp options are available.
