This is a mounting system for iPad Pro to watch your iPad comfortably while laying down on those lazy days. The bars that make up the extensions between the printed connectors are for .5" square stock aluminum:
2qty @ 8"
2qty @ 11.25"
2qty @ 20.75"
use 4qty (1/4 x 20) 3-1/4" bolts and nuts at the base to make the clamp assembly at the bottom. Then you will be ready to watch spooky movies on Holloween. Even every other day of the year.
