This is no ordinary Gooseneck Car Mount, this is a reinforced Steel Gooseneck which mounts to your floor or is bolted to your passenger's seat. It's still as flexible as a non-steel gooseneck mount and is ideal for use for those who operate heavy machinery. Simply place your iPhone 4 into the Custom Fit Cradle and then attach to the Steel Gooseneck. No drilling is required, simply use the included bolts for a secure hold. The Gooseneck measures 15" and is easily manipulated to your choice of viewing positions. Safety first. With Amzer's 15" Steel Gooseneck Floor Mount for your iPhone 4!
