Based on their classic clamp and knob, the Delta 3 Arm Side Ball-Joint Clamp from Aquatica's Technical Lighting Control series is meant to be mounted on the side of a lighting arm segment. This allows for an additional attachment, such as a focusing or video light to accompany your strobe. The clamp is intended to maximize your lighting possibilities while keeping your setup streamlined. It accepts ball mounts with 1" diameters.
With this clamp, Aquatica has improved on the design of their previous models by providing a smoother, spring-loaded hold on ball mounts, as well as a finer screw thread on the tightening knob. Built to last, the unit is made from aluminum that has been hard anodized and treated with Teflon for resistance to corrosion and other wear and tear.
