RAS Complies description received in a suitable packaging and on time all at a reasonable price.

Easy assembly:
The key 6 sides need being provided, it only remains to have a Phillips screwdriver to attach the cable guide 4 (visible in the photo: 4 small grommets located in the joints) and screens on the bracket (screws included)
Tighten the clamp seal block (Recommended martyr boards if the office is fragile) so that the mast is stable and remains perpendicular to the fixing plane.
If like me your screens are different they will not necessarily be at the same level but I'll tinker with an offset vesa metal plate pierced with holes 8 to make up the difference.
The six vertical rotation axes allow optimal placement of your screens
The two knurled knob bolts are used to adjust the tilt of each screen and block the movement of the cup when the setting is done.
