Ram Add-A-Ball Accessory Ball for B Size Socket Arms
Connect another device to your existing RAM Mount with the Ram Add-A-Ball Accessory Ball for B Size Socket Arms. This ball base adapter consists of a 2.54 cm ball connected to a 1/4"-20 threaded bolt with a length of 4.06 cm. The thread of this ball replaces the bolt in any B Size arm, and the ball connects to the centre of the arm on the opposite side of the tightening knob. If you want to mount more than one device but can't find multiple mounting points on your motorcycle or vehicle, this base is the ideal accessory to connect both devices from a single mounting base.
