The FSF Flat Screen Furniture Mounts let you elevate your flat screen monitor off of an existing piece of furniture with an elegant and clean appearance. Cable are cleverly hidden-running through the mount and furniture top. The mounts swivel up to 90 degrees allowing for the best viewing angle. The FSF12 mount is similar in design to the FSF14 except that the tubing does not pass through the countertop. Also, the FSF12 has a rectangular mounting plate instead of a circular dress ring. The mounts require an adaptor plate.
