These 6 casters fit the Torrey brand products only!  The casters allow you to move your Torrey products easier.  Certain model coolers and freezers require 4 or 6 casters.  Please look at the model fitment chart below.   Please note: Casters add an additional 3.5 inches in total height to your cooler. Kept that in mind if you are trying to fit cooler in a tight space.
