The RAM X-Grip Phone Mount with Vibe-Safe and U-Bolt Base from RAM MOUNTS holds smartphones up to 3.25' in width and 2 lb in weight in either portrait or landscape views. The medium arm gives you freedom of mobility and keeps your phone within reach while out of the way. A U-Bolt base makes this mount work well with handlebars on bikes, motorcycles, and more that have rods 0.5 to 1.25' in diameter. Its stainless steel and high-strength composite construction adds durability to the holder itself, and an optional tether can be used to hold your phone in place.
