All Bartlett Pole Pruners are professional grade for the professional arborist. Our round fiberglass poles are light, strong, and stiff. Featuring the Fred Marvin PH4 pruner head, the opposing head comes with a BRASS ferrule that can quickly attach to another Bartlett extension pole. Why BRASS? These quality Bartlett Brass connectors will not break, bend, or corrode. These connectors will outlast all others - aluminum is cheaper, but your time isn't. Bartlett Brass. . . strong, durable, and reliable! Poles longer than 8 feet must be shipped Freight.
