Summit's long-running successful line of commercial sliding glass lid chest freezers offers outstanding value, but with a long list of standard features: including a lock, drain, casters, 19 7/8" deep interior (for two tubs of ice cream back-to-back), aluminum frames with reinforced corners, plastic coated runners for easy gliding and durable aluminum interiors. Large fan cooled compressors for better performance in hot and humid conditions. Optional baskets are available. U.L. and U.L. Sanitation approved. Summit commercial freezers are built to commercial standards, with large compressors, more cooling coils, and thicker interiors. Please don't compare them to some competitors who start with household chest freezers and add glass lids.
