Zero Touch Key

A locking device created to stop patio umbrellas from spinning wildly when tilted to block out the sun's rays. It's specifically designed for use with 37mm umbrella poles, although it may also work on sizes ranging from 36-38mm - just be aware that this hasn't been thoroughly tested yet.
