Patio Umbrella Lock Designed to Prevent Unwanted Spinning When Blocking Sun's Rays. Crafted specifically for a 37mm umbrella pole, this innovative lock may also work effectively on poles ranging from 36-38mm in diameter. Note that its performance on these larger sizes has not been thoroughly tested, however.
