WALI Dual Monitor Wall Mount, Single to Double VESA Bracket Adapter, Horizontal Assembly Arm for 2 Screen up to 27 inch (012ARM), Black

Wall Mount: The dual arm can be mounted on concrete/brick walls only, helping you to fix two screens at the same time. Compared with a straight wall, the curved design of the arm can optimize the visual limitation on the basis.
Horizontal Adapter Arm: The dual arm also can convert a single monitor mount into a dual monitor mount with the middle VESA plate. One thing needs to check is your existing mounts hole pattern is 75mm or 100mm.
Compatibility: The mount fits two monitors up to 27, support weight up to 22lbs per arm, and VESA 75x75mm to 100x100mm. Can tilt +45°/-45°, swivel +15°/-15°, and rotate +180°/-180°. The adjustable distance between two VESA plates is 16 to 28.5 inch. (Note: With wall mounted, the tilt and swivel function will be more limited. )
Ergonomic Design: The curved arm and adjustable VESA plate can provide you maximum adjustment space to find a comfortable and correct position, which will reduce neck and eye strain.
