Custom Umbrella Lock Prevents Spinning Chaos Designed specifically for 37mm umbrella poles, this ingenious lock keeps your patio umbrella firmly in place when tilted to shield against the sun's harsh rays. While it may also work with slightly smaller or larger pole sizes - ranging from 36-38 millimeters - its effectiveness has not been thoroughly tested.
