The smooth operating arm of the SM-ART1-M allows easy extension of flat panels to make side action or around the corner viewing a little more tolerable. Having both a great extension coupled with a low profile when closed helps make it such a Strong solution. With a slight variation to the ART1-S model, the head is detachable from the body making it easy to mount to a single stud then hang flat screen. Simple. It's tough to get motion mounts completely flat to the wall, but a 2.9" profile helps hug it tight yet allows enough room for cables to sit behind it. Whether the movement is too stiff or too loose upon installation, simple adjustments along the joints allow you to adjust on the fly. Providing up to a 270 degree swivel and a 15 degree forward tilt means you have a pretty easy time offering a great viewing angle at almost any location. A spring-loaded screw included on the back of the mounting head ensures the display stays put once mounted. And since it is attached, you don't have to worry about searching for it.
