4" Square metal Lazy Susan revolving base attachment (5-1/2" diagonal measurement). Rounded corners. Corners have holes for small screw (not included).
Made from corrosion-resistant galvanized steel with quarter-inch balls that can be greased to dampen noise. The swivel bearing design has a deeper race groove, encapsulating the balls more effectively and allowing them to move more smoothly.
Felt or cork "feet" can be attached to the metal to protect table top surfaces, etc.
Attach to the bottom of a slotted wooden base to make any wooden base a revolving base.
The 4" size attachment works best on the 7" - 8" bases.
