Our Homeowner Series Poles utilize the same locking mechanisms that many pool professionals use on a daily bases all over the United States. All homeowner poles are thinner and lighter than our service poles, but still have the High Quality 100% USA made materials. This line was made for the homeowners who are looking for better equipment and are sick of wasting money for low quality products typically sold at box stores. EliptiLock™ with its patented design builds the lock into the tubes. There are no parts to fall out or break! The outside tube is formed slightly out of round and the inside tube is equally out of round which creates the friction for the lock. Over the past 40 years, the Eliptilock has become an industry favorite of many professionals and out sells any of our other poles.
