Refrigerated vans can be outfitted with a variety of doors from the sides, back, and front. A roll-up door lifts from the back or side to allow easy loading and unloading. Swing doors do just what their name suggests; they swing open from the back or sides of the vehicle, allowing access to the goods. Panel swing doors also swing open; however, both doors fold like an accordion as well. A van with a single-panel side door will open from the side, usually right behind the passenger door of the vehicle. This gives you an extra point of entry, so you can access the goods from the front of the van body as well as the rear. Finally, a narrow opening swing door is a small door at the side or rear of the vehicle that acts as a quick point of entry.
