The RAM-B-272 marine grade aluminium base consists of a 1″ diameter ball and base with a 9mm fixing hole. This part is often used on motorcycles attaching to the mirror frame but this is by no means it’s only use – it can be attached to any bolt from 6 – 9mm – the only limit is your imagination. Pictured below with a RAM X-Grip Smart Phone Holder with 1″ Ball and RAM 1″ Short Arm, it can be linked with any length of arm and mount.
