This standard style base is available in two weights: 35 lbs. (with a 1.5" stem) and 70 lbs. (with a 2.0" stem) Made of pure steel available in a black matte finish. These are shaped perfectly for fitting under our fine teak tables, including the ones without much ground clearance. Both styles include our patented Dual-Purpose Stem, which allows you to use the base with a free standing shade umbrella (70 lbs. base only) or reduce it to use under a table.
