Marvin pruners have set the standard for pole pruners since 1943. The PH-4 is their most popular pruning heads, sporting a razor sharp blade that cut limbs up to 1-1/4" in diameter with ease. The PH-4R is lightweight (a complete cutting head weighs only 1 lb. 12 oz) and their slim design permits access to many areas not reached by more bulky pruners. The PH-4 pruner head has a round casting for easy mounting to fiberglass or octagonal wood poles. The cutting blade is made of high-grade steel to permit several resharpenings. Add a quick change adapter and you can snap into any 1-1/4" female pole. PH-4 pruning head is also known as model PH-4R. Made in the U.S.A.
