Mobile stainless steel trolleys with side guide rails for trays or baking sheets, ideal for easy transport, cooling or staging of goods. The frame is made of welded or bolted AISI 304 stainless steel, providing robust stability. The trolleys are equipped with swivel castors, two of which have brakes, and feature non-slip, non-marking wheels. Optional bumpers and push handles can be added. Tray capacity and spacing between levels vary depending on the model (e.g. 10–20 levels).
