Top plate’s size is slightly bigger than an arm’s base. Bottom plate has the same size as an arm’s one. I don’t know what I paid for Updated: Changed my review. The product still doesn't meet my expectations, I don't think I will buy again. BUT the manufacturer is very customer oriented. They contacted me and offered to refund my money, although I did not ask for and do not want a refund because I am really happy with the arm. Their attitude towards customers is like no other. They did not ask me to change my review, but I am so surprised they reached me out that I want to do it.

Bought this for use with my 57" monitor so it needed the reinforcement on my desk. Does the job well.

Soweit alles gut, hält meinen 49 curved Monitor zusammen mit entsprechenden Arm. Gute Gleichverteilung am Desk. Das einzige was ich komisch finde ist wieso dieses Ding nicht zusammen mit dem Arm verkauft weil eigentlich braucht man es ja.

A great item to use with a Invision MX 900 very heavy and well made and the sticky protection pads that protect the top and underside of desk. Very satisfied.

Il a une erreur dans la cotation de la "bottom reinforcement plate" de la photo . La plate mesure 7cm de large et non 1,5cm.

裏面はラバーコーティングで完璧。他社製のゴムずれ問題は起きない。上辺が、少し大きめだが、ロングポールでも安定で納得。他社製アームも、コレ一択。
