Velocity Mount Smartphone Tripod Mounts are precision CNC machined from solid aluminum and finished with hard anodizing for exceptional strength and rust/scratch resistance. We offer two versions: Smartphone size and Ipad/Tablet sizes. The product will fit nearly all smartphones on the market from 2.2" to 3.4" wide, with or without a case. May also work with phones slightly outside that range depending on their thickness. The Velocity Mount smartphone holder can be attached to any standard tripod (1/4-20) and comes with an additional (1/4-20) female thread for additional attachments and can secure your cell phone for photos, videos or being used as a webcam or car GPS. The rubber pads protect your phone's edges including the new curved edged phones, and nothing contacts your phone's screen. Our unique V-shaped groove also leaves space for edge buttons. Compatible with all Apple iPhones, Samsung Notes, Samsung Galaxy, Google Nexus, Nokia Lumia, HTC, Motorola, LG and many other phones and phablets.
