Skimlite Eliptilock™ 3008 8'-16' Tele Pole 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. This lock is a quick on and off lock ideal for jobs that need to be done fast. Whether you choose our lighter weight (3008/3500) or heavy duty versions (3006/3118/3516) you will not be disappointed with this industry favorite that out sells any of our other poles. Skimlite takes pride in manufacturing high end service and commercial poles that will hold up to everyday use and can be depended on in even the most demanding applications. We understand that when it comes to cleaning a pool a pole is one of the most important tools for any professional. Not only is a pole one of the most important tools, but we also understand the importance of a dependable pole that fits individual and specific needs.
