The car seat rai mount and extension bracket is made of strong aluminum, and is ideal for those who need easy access to their Motorola Wave TLK100 or SL300 and Speaker mic but prefer mounting it somewhere other than the windshield or dashboard. In addition to cars and trucks, this pedestal is recommended for fleets and service vehicles. Brackets are included for various seat rail configurations. Use a socket wrench to install the mount to the car’s seat rail. Loosen the passenger seat track bolt, insert the included seat track bolt bracket, and then retighten the bolt.
