FAQs

What size is the centre hole, and is it threaded? The centre barrel portion is 30mm (1.18") tall and does not come threaded.

Will this work on top of the Tele-Pole? No — the RAM-B-289U isn't compatible with the swing arm at the end of the Tele-Pole. The RAM-289U, with its larger 1.5" balls, works well with the Tele-Pole and swing arm assembly instead.
