Included:

• 1 x RAM Square Post Clamp Base for 1.75"–4" Posts, C Size (RAM-247U)
• 1 x RAM Medium Double Socket Arm, C Size (RAM-201U)

A post-clamp mounting combination with an adjustable RAM-247U base, medium C size arm and round output plate. It fits square-post widths of 1.75"–4" using the slotted clamp base.

The rubber ball-and-socket joints adjust at both ends of the arm and help dampen shock and vibration.

Check the complete assembly’s weight and loading conditions. The weakest component and mounting surface determine the usable capacity.
