The pre-attached vertical rails can be easily removed with our provided M4 hex key as seen below.
We recommend re-using the provided screws from the vertical rails to attach Vestaboard to your alternate 400mm x 400mm VESA system. Please check with the manufacturer of the VESA mount you intend to use to confirm the provided Vestaboard screws (M6X0.75 thread, 10mm long) are compatible with the mount sold to you.
If you proceed with the screws provided by the VESA mount manufacturer, confirm they do not exceed 10mm in length and match the 0.75mm thread, as there is significant risk that longer screws will pierce the Vestaboard backplane.
Ensure the replacement rails or brackets of the third-party VESA mount system sit snug against the Vestaboard. Never over-torque these screws. We recommend using hand tools (and never power tools) to prevent over-torquing.
Save your vertical rails and screws should you ever want to mount on the wall in the future.
