Shadow Mounts from Dayton Audio place the focus on your flat panel television—not the mount. Heavy-duty, solid-steel construction provides you with peace of mind knowing your HDTV investment is held securely in place for years to come. Ceiling mounts are a great option for placing an HDTV in commercial and industrial settings. Adjustments are accomplished on the mounting arms by a quick turn of the knob, no tools required. The patent-pending design with the exclusive Rail Clip™ feature eliminates clumsy set screws while the heavy spring tension holds your television securely in place with simple finger-tip control. Each model features a locking system for security, anti-bending support on the included ceiling plate, and a double locking column to virtually eliminate flexing. Lag bolts, concrete anchors, Phillips head mounting screws (M4, M5, M6 and M8), safety bolts, and easy-to-follow instructions are included.
