The construction of this turntable lends it to outdoors as well as indoor use. Steel ball bearings are fairly well protected from moisture to resist rusting. A large coin-slot screw provides ready access for cleaning and maintenance. A convenient thumb-screw locks the bable in the desired position when working or displaying Bonsai. 7-1/4" diameter top, 8" diameter base, 1-5/8" high, holds over 25lbs without binding.
