This sifter’s framework is LASER CUT from 14 gauge steel. Each corner has been welded and then ground clean and smooth, there are no sharp edges. The bottom screen is a heavy gauge, stepped mesh that shreds sod and breaks up dirt faster than a smooth mesh. It has a 3/4 x 1/4 inch diamond mesh pattern. The bottom of the sifter measures 6 1/2 x 8 1/2 inches. All four sides are tapered which allows you to use any side for scraping and scooping up dirt.
