The US Weight 80 Pound Free Standing Umbrella Base is crafted with a high-density polyethylene shell with UV protection that will not rust, dent, or fade, and can withstand the elements in any weather climate. This heavy and stable base was prefilled with 80 pound of high-strength concrete.  

Easily transport and setup the base with the removable wheel on bottom and hand grips for easier mobility. The 20.5″ diameter base features a 14″ high stem that accommodates poles from 1 ½” through 2″ thick. Inside the stem is a plastic post protector for the umbrella to rest on instead of a screw leaving the pole undamaged. The stem features two knobs made of polypropylene that tighten the umbrella securely in place for added stability and support. All of the steel components are made of grade 304 stainless steel. Grade 304 stainless steel is also used in aerospace engineering and surgical instruments and will not rust. The umbrella bases come in four colors – black, bronze, grey and white.
