Patio Umbrella stand (Katy gate)

Hi everyone, I’m looking for a heavy outdoor patio umbrella base or stand for my backyard, similar to a classic round black weighted base with tightening knobs. As long as it's in sturdy, usable condition to hold a outdoor patio umbrella safely, any similar style works great. I can pick it up promptly at a convenience time and location for you, so please reach out if you have one you no longer need. Thank you!
