Finish off your Ion Arm with this precision machined end cap! Machined from aluminum and brass, and includes accurate socket head cap screws (#10-32 threads). Brass rods are threaded and screw tightly into the aluminum block for maximum security.

The GB1 version includes the small Clippard elbow with a pre-drilled and tapped hole for installation, and the GB2 version includes the larger Clippard elbow, ready for you to install on your Ion Arm. (GB2 elbow is installed on the Ion Arm itself, so no elbow hole will be drilled and tapped on the Cap. The GB2 elbow requires a 1/8-27 NPT pipe tap.)
