MARVIN fiberglass professional pole series are lightweight, extremely durable and available in lengths from 4' to 6'.  Sizes up to 12' may be special ordered. (Allow two weeks for special orders.) The wall thickness is 25% greater than the average pole to ensure a ridged feel. The poles feature air craft grade aluminum extension couplings to connect two 1 ¼" poles. Both couplings are locked by a spring clip that is easily controlled with thumb and forefinger.
