Not suitable for 400mm VESA,
Verified Purchase(What is this?)
This review is from: Av:link 129.352 Dual Arm Support Bracket (Accessory)
Nicely made, but hopeless for 400 Vesa.
Firstly the 4 detachable arms are difficult to align. You have to tighten them just enough to function, then fix in place and gently remove and retighten hoping that they do not move. Then the screws supplied are completely the wrong diameter for my Samsung 32" screen needing 8mm not 4mm as supplied. The holes in the arms are also too small to take the screws. The spacers supplied are also inappropriate.
Will be sending this back ASAP
