Wooster tools are held in place by a special bayonet Grip Tip™ that prevents them from twisting or loosening. R042 Conversion Tip is stored at the end of the grip, making all threaded tools GT compatible. With a single push, you may instantly change tools. The fiberglass-reinforced hexagonal aluminum inner pole avoids twisting; the robust fiberglass outer pole and nylon lever. Easy to adjust in 6" increments with a touch of the thumb, then locks firmly in position.
