EliptiLock™ Elite 8' to 16' Tele Pole - 3118 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. This lock is a quick on and off lock ideal for jobs that need to be done fast.
