This mount is a professional designer series mount featuring elegant design, cable management, and rock solid movement.  This mount is quite comparable to the Omnimount CL-L mount sold elsewhere for $300-$500.  We believe that is it the best arm mount available for 26-42" displays using a VESA 100 or 200 hole pattern and weighing up to 125LBS regardless of price.This is a truly professional mount providing the best available solution for utility and style for 26"-42" displays using a VESA 100 or 200mm hole pattern. Most LCDs up to 42" utilize a VESA hole pattern. If the mounting holes on the back of your display are about 4" apart, that is VESA 100. If they are about 8" apart, that is VESA 200. Some displays are 100X200 and this mount fits those as well. If your display is VESA 100 and weighs less than 35lbs, you may be able to use our single stud arm product which costs less. This mount is ideally suited for 15"-24" displays but can mount certain larger displays up to 32" using a VESA 100 hole pattern. But our recommendation for 26"-42" is this mount. If your display does not use a VESA 100 or 200 hole pattern, we sell a number of Universal Arm Mounts which will support any hole pattern up to 29" wide and 19" tall.
