The clamp-on fishing pole holder keeps a good grip on the pole while it makes the reel available for one-handed operation. The pole can be easily removed from the holder. A clamp with a large wing nut makes it adaptable to any tubular wheelchair bar 7/8 to 1 1/8ù (2.2 - 2.86 cm) diameter. The holder is also a perfect fit for use on lawn chairs or beach chairs.
