This is a replacement Monitor VESA Plate, in black, for select Mount-It! monitor arms. It offers VESA 75 x 75 and 100 x 100 mounting patterns and supports up to 33 lb, or as much as your monitor arm supports up to the 33 lb maximum. The plate features heavy-gauge steel construction.
As Described. It fits into the snap-in arms for Vesa mounts, and the holes work.
Somehow lost the VESA mount plate & adapter for my Monoprice Workstream monitor arm (probably because I was able to move the monitor with adapter plate attached to a different arm). Mount-It! had this part which looked like it might work with the Workstream, and when I got the package today it fit perfectly! Suspect this will also work with Fully Jarvis mounts as well, since I think that's where my 'missing' VESA adapter plate & mount went.
