Securely attach your phone to a pole or post with this Pole Smartphone Holder from K&M. The holder attaches via a manual clamp with a knurled tightening screw, and is compatible with poles/posts up to 1.18" in diameter. To mount your phone in the holder, simply place it on the individually adjustable supports and squeeze the clamp closed. Once set up, you can easily adjust your phone to the perfect position. The integrated ball head allows you to tilt the holder up, down, or rotate it 360°. A 3.94" flexible arm connects the holder to the pole clamp, allowing for even more adjustment as needed.
