The Roller Dog RDB18SS-SG Commercial 18 Hot Dog Roller Glass Protective Guard is an essential accessory for your Roller Dog 18 hot-dog roller. This guard improves sanitation and safety by shielding the rollers with a layer of extra-strength clear tempered glass. This helps to eliminate germ contamination (with proper use) and prevent accidental burns. Stainless steel sides provide a rigid frame. Note: includes guard only; roller not included.
