RAM Mounts U-Bolt / Strap Mount GoPro Kit The Ram-B-149Z-2-Gop1U, is composed of a steel strap base, u-bolt bases, a double socket limb, and a 1-inch diameter sphere that complements the GoPro Hero attachment perfectly. The mount is crafted utilizing the RAM system, marked by a 1-inch diameter patented rubber orb and socket, buoyed with adjustment spots nestling at both closures of the double-socket limb. This assures almost limitless adjustment and flawless viewing angles. Developed for an unblemished installation, the mount supports most typical roll bar dimensions, paving the way for the positioning of the RAM rubber ball base. If needs be, the mount can be aligned to the handlebars of smaller diameter by deploying the enclosed hardware. The GoPro Hero adapter can be latched onto the underside of the camera directly, effectively replacing the factory mounting bracket.
