Sörbo knows innovation! It’s a dream to work with. The first twist-lock pole that actually locks reliably and securely with a quick twist. This high-torque, heavy duty lock is made for the high performance window cleaner. When it locks, it’s locked. The first-of-its-kind, exclusive twist-lock is anodized aluminum fine-thread (will need to be lubricated every 6 months). Please use the specified lubricant that we will provide. We suggest that you unscrew the collar, then clean threads and apply the specific lubricant (Item.1387A). SAFETY WARNING! Danger – Electrocution Hazard – Never use when power lines are over head! Sörbo invented the California Dream Pole in 2015.
