The RAM® No-Drill™ RAM-B-316-1-202U vehicle mount consists of the RAM® POD™ I base, 18” rigid aluminum rod, B Size 1" ball socket arm, and a round ball plate. The base of the mount connects to your seat rail without any drilling necessary. The 18" rigid aluminum rod can be bent to position your device an ideal viewing and operating angle. The 2.5" diameter round base adapter contains the universal AMPS hole pattern. For proper fit, make sure your vehicle has an appropriate bolt to mount the base securely. The RAM-B-316-1-202U is not compatible with 2014 and newer Chevrolet seats that have the seat hook system.
