Material: High strength composite / rubber fins Top plate diameter: 3" approx. Diameter across fins: 3.75" approx. Height: 4.75" approx. Let your imagination run wild with the RAM-A-CAN II™ universal cup holder mount! Designed to provide yet another smart way to mount mobile electronics, the rubber fins on the RAM-A-CAN II™ are designed to deform when inserted into a cup holder providing a tight snug fit whilst remaining instantly removable. The centre hole is 'blind' allowing use of RAM suction cup mounts RAP-224-2 and RAP-224-3 to provide a ball base for compatible B series (1" dia. ball) components and third party suction cup mounts including TomTom and Garmin. 2 indents on the top surface indicate the attachment point where the supplied self tapping screws can be used for B series ball bases with screw holes RAM-B-138 and RAM-B-202. * Rubber fins can be cut with a blade to reduce the diameter if required. * Garmin suction cups must be positioned off centre to allow airtight fixing. * RAP-224-3 suction cup will overhand the edge by approx 1/8".
