You pick. The unfinished pine rack stands 9-1/2" wide x 7-3/4" high with (7) 3/4" ID ports on the top, (6) 1" ID ports on the bottom, (6) 2-1/4" drying rods on the back. The fluid-resistent, treated 2-tier rack stands 10" wide x 8-1/8" tall with the same complement of ports and rods, except that the drying rods are 2-3/4". If you don't do lab work, think spice rack or post-modern flower arrangements (get tubes with stoppers right here), or a pen/marker caddy.
