CorSec Engineering have completed the first prototype Clear Omni-Stand Rod:
From their announcement:
The rod consists of 1/4″ diameter clear rod with steel threads at either end. This should still provide good strength and have the added benefit of being clear. They will be cheaper then the metal rods and only a 1/16″ increase in the diameter. We are working on reducing the thread insert depth to give it a cleaner look. We hope to be ready for full production really soon.
