This hardcoat anodized aluminum mounting block and bracket can be used as a fixed mount for flowing, or as a storage bracket for the Hemisphere monitor. This mount can be bolted from the front of a sufficiently rigid surface, by adding two ½"-13 tapped holes; for locations where the back side of the mounting surface is inaccessible. It can also be bolted from the back side of a surface by drilling two (2) 5/8" holes, and screwing 5/8-11 bolts into tapped holes on the bracket.
