Yep portable hot box, sometimes used to keep pizzas hot at like a ball game or what not...
it can also be used for a proofing oven with a single sterno or tray of boiling water.
be careful though, it gets hot as hell after a few hours of use. I used them for catering and 1 - keep a tray of water directly above the heat source..2 - if u load it with hot food AND put the sterno under it, it will continue to cook.
What's the make of it? That would work PERFECT for me!
Ill look today, I think im going to clean it up today
