Nocturnal Lights 12 Aluminum Ball Joint Underwater Strobe / Video Arm for Underwater Ball Joint Arm Strobe and Lighting Systems

This Nocturnal Lights Aluminum Double Ball-Joint Arm Section is a 12" section used to join with other components of the Nocturnal Lights ball-joint arm system. Use a Nocturnal Lights ball-joint clamp to join with other sections. The arm is constructed from light but sturdy anodized aluminum. The 1" ball has an o-ring; this helps the clamp to hold the section in position without slipping.
