The Moffat M234580 roller catch secures the door in its closed position on compatible commercial convection ovens. Its roller mechanism engages with the corresponding door fitting, helping keep the door aligned during cooking cycles. When the door is opened, the catch releases from its engagement point to allow access to the oven cavity. https://partsfe.com/moffat-m234580-convection-oven-roller-door-catch/1-M234580.html
