The RAM® Handlebar U-Bolt Double Ball Mount with AMPS Plate provides a rugged and adjustable mounting solution for GPS units, phone holders, and device cradles that use the universal AMPS hole pattern. Designed for motorcycles, ATVs, bicycles, and other vehicles with round rails, this mount attaches securely using a zinc-coated U-bolt base that fits handlebars from 0.5" to 1.25" in diameter.
At the top of the mount, a 2" x 1.7" square AMPS plate with integrated 1" RAM ball allows you to attach compatible device holders, GPS cradles, or accessory plates. The RAM patented ball-and-socket system with a standard-length double socket arm allows near-infinite adjustability, letting you quickly position your device for optimal visibility and safe operation while riding.
Constructed from powder-coated marine-grade aluminum, this mount is built to withstand vibration, weather, and demanding environments. The included rail adapters and protective caps help ensure a secure and clean installation on a wide range of handlebar sizes.
This mount is ideal for riders who want a durable handlebar mounting system with universal AMPS compatibility for GPS navigation units, phone holders, cameras, and other accessories.
