The SM-ART1-S is a perfect, low-profile 'tilt & turn' solution for those installations when moderate adjustment is all that's needed. With a new mounting head and wider VESA range, this mount will fit most 13-27" flat panels. You have to love technology and the ever changing designs of flat panel manufacturers. The SM-ART1-S mounting head has been modified to accommodate flat panel mounts whose VESA pattern is 75 X 75, 100 X 100 and now 200 X 100! It's quite simple…we provided a separate wall plate for lightning fast installation of the entire mount. Just mount the plate to the stud, attach your display to the mount head and slide on the wall plate. Snap - your done! Quite often there will be times were the movement of joints out of the box is either too stiff or too loose for the desired application. Located at each joint are points to tighten or loosen the resistance to accommodate different flat panel weights and personal preferences by your customer. To further assist a quicker installation, a small bubble level has been included for those that like to eyeball.
