RAM-B-149Z-QU1U – RAM® U-Bolt Rail Base with Medium Double Socket Arm
The RAM-B-149Z-QU1U is the no-frills version of our U-bolt rail mount: a zinc-coated U-bolt base and a medium B-size double socket arm, ending in a 1" ball ready for any RAM B-size cradle. No diamond plate, just the base and arm, which makes it the most affordable way onto a bar for an X-Grip, GoPro adapter or device cradle. It clamps round rails from 12.7mm to 31.8mm (0.5" to 1.25").

FAQs
What's the difference from the RAM-B-149ZU? This one has no diamond plate. The arm ends in a bare 1" ball that plugs straight into a RAM cradle. If you need a flat AMPS plate to bolt a holder to, choose the RAM-B-149ZU instead.
