CorSec Engineering has a new telescoping rod with a screw connection at one end for their omni-stand.
From the update:
We have added another type of Telescoping Rod to the Omni-stand line. The head on this setup is a screw that is compatible with any of the Omni-Stand Mounts. These rods provide a secure connection that allows you to get larger kits off the ground without worrying about the magnets letting go. It works great with 1/72nd scale fighter kits!
