Jameson's 70-102 Pole Mount Bracket is designed to save vertical space on crowded joint occupied poles. They are contoured to fit pole for maximum stability. The nylon strap and ratchet make the brackets easy to use. The ratchet strap weighs less than chain straps and will not damage existing cables. It can be adjusted to work from the right or left hand side for convenient operation.
