RAM-B-149ZU – RAM® U-Bolt Rail Base with Diamond Plate and Medium Arm
The RAM-B-149ZU is a complete handlebar and rail mount: a zinc-coated U-bolt base, a medium B-size double socket arm and a diamond AMPS plate, ready to take any RAM 1" ball cradle for a phone, GPS, radio or action camera. It clamps round rails from 12.7mm to 31.8mm (0.5" to 1.25") on bikes, motorbikes, boats and kayaks.
Key Features
Zinc-coated steel U-bolt fits rails 12.7mm to 31.8mm (0.5" to 1.25"); a composite adapter narrows the clamp down to 12.7mm (0.5")
Diamond plate with the industry-standard 2-hole AMPS pattern connects to a huge range of RAM and third-party cradles
Medium B-size double socket arm with RAM's rubber ball-and-socket joints for near-infinite adjustment at both ends
Powder-coated marine-grade aluminium, built for vibration and weather
Backed by RAM's lifetime warranty
Works With
The 1" rubber ball is RAM B-size, so it takes any RAM B-size cradle or holder, plus thousands of third-party holders that use the AMPS hole pattern. Pair it with an X-Grip, Quick-Grip, Finger-Grip or a device-specific cradle. Prefer a round plate instead of the diamond? See the RAM-B-149Z-202U round-base version. Need a shorter or longer reach? See the short-arm RAM-B-149ZU-A or long-arm RAM-B-149ZU-C.

FAQs
What cradle do I need? Any RAM B-size (1" ball) cradle for your device. The diamond plate also bolts to AMPS-pattern holders if you already have one.
Will it fit my handlebar? If your rail measures between 12.7mm and 31.8mm (0.5" to 1.25") around, yes. The supplied composite adapter helps on thinner bars.
