This Avantco 360CASTBRKDF 2" caster is a direct replacement for the one that came with Avantco DFF, DFC, and ADC series ice cream freezers. The casters are a vital part of your unit, making it possible to move the item during cleaning and installation. It installs with a mounting plate and can swivel to make maneuvering it around turns and obstacles easy. A brake lets you hold the cabinet in place when you want it to be stationary.
