Our Adjustable Device Mount is a new and improved way to build a flexible arm stand for your iPad, tablet, eReader or other device. It is spring-loaded and features soft rubber bumpers for a secure hold. Accomodates devices up to 5/8" thick with one dimension between 5-1/2" and 11-1/2". The Adjustable Device Mount attaches to SnakeClamp brand flexible gooseneck arms with a ball and socket arrangement. This allows you to tilt, rotate and swivel your device for precise positioning: Simply pull the end brackets apart, insert your device and release. As shown here this iPad can be attached across either the short or long dimension. As long as the dimension is between 5-1/2" and 11-1/2" you can attach to it! Here an iPad is attached across the long dimension: And here the same iPad is attached across the short dimension: Please contact us at support @ snakeclamp.com with any questions.
