See where the Mat1 arrow is pointing on picture? Now look just below that arrow on picture andyou will see a threaded hole. Looks like that is the back side so no hardware goes in that hole from the left side. My question is, do you think you can make a aluminum skinny long arm, use a die to match the threads pattern andthen screw itinto those threadsand make it a full containment drop away? I know the hole looks a little too low, but if you came out of the threads, went 90 degrees up and then back out over the shelf itshould work.
