Ideal use cases

• Marine electronics: chartplotters, fish finders, and marine radios on boats

• Industrial and commercial: mounting cameras, sensors, and small monitors
• Recreational: securing action cameras or handheld GPS devices on bicycles or motorcycles

Good to know

This kit includes the arm and two bases only; a device cradle or holder is required to complete the mount. The bases feature a 4-hole AMPS pattern for secure attachment to flat surfaces. Minor assembly is required, and all necessary hardware is typically included. The RAM Mounts B-Size components are interchangeable with other B-Size accessories, allowing for future expansion.
