Where can I buy a electric screen adjustment wand?
Subject line says it all
TL;DR look at the YouTube links, see the wand? I want that! Where can I buy it!?
The wand is used on electric projector screens to adjust the rise and drop limits of the roller motor since those controls can be obscured by installation
You can see some good examples of these wands in use with the following videos
I adjusted all the videos to start at the relevant parts so you don't have to watch for more than 2 seconds on any single video
