Add Weight to Monitor Arm, iPad/Tablet Mount


  • Add 4.38 lbs weight to monitor arm or iPad mount with this adapter plate
  • Helps monitor or iPad mount reach minimum weight requirements
  • Please ED-WGH1 if you want a lighter plate



The ED-WGH adds 4.38 lbs (VESA plate with 100x100, 75x75 pattern) weight to your monitor arm or mount. If your monitor does not meet the minimum weight requirement for the arm, it will be too light for the arm, making it spring upward. Then the whole purpose of an adjustable mount is lost. Adding the ED-WGH to your monitor will make it heavy enough so that the arm stays at your desired height.

Works as advertised

I bought a sturdy arm for the Mac Studio Display. However the Studio Display is much lighter than expected. When looking for a solution I came across ErgoDirect and was able to the weight which fits the VESA mount perfectly and flush. It was the weight I needed to make the display move smoothly on the arm. Also the communication with ErgoDirect was extremely friendly and helpful.

VESA Adapter Plate adds 6.5 lbs which might not be needed if you have an older monitor

by Cathy S, Oregon, May 16, 2016

Screws used to connect the 6.5 lb adapter plate to the back of the monitor did not take into account the depth of the mounting fixture attached to the monitor plus the total depth to the screw mount on the back of the monitor. (the screws needed to be about 4mm longer) Plus, it seemed as if the 7mm screws used for the conversion plate were barely going to hold all of combined weight. I ended up in the final build not using the 6.5 lb as the 24in monitor provided enough weight. I'll keep the weight in case I swap out old monitor for a new lightweight style as I notice the backs on the newer monitors are flush as the pedestal is attached towards the base.

Saved us a lot of money

Thank you for having this and getting it to us so quickly, we ordered heavy duty monitor arms for our customer, and they decided to switch monitors before the order arrived and went to much lighter ones. If it hadn't been for this solution I would have had to reorder a lot of monitor arms which would have cost us a lot more money!
