There’s nothing worse than having to constantly retighten a tool that keeps spinning off while you are trying to use it. For example, if you’re constantly having to stop painting a wall to tighten the roller frame back onto the pole, or if you’re sweeping the garage floor and the broom head continually falls off the pole, it’s not only time consuming but irritating. To solve this problem Mr. LongArm’s Heavy Duty and Professional extension poles come equipped with a special feature on our standard ¾” metal threaded ends. It’s called a Lok-thread and was designed to prevent threaded tools from loosening during use. No more stopping what you’re doing; attach your tool and get to work!
