This commercial-grade concession window features a thickened aluminum alloy frame that resists rust and wear. The window offers an 85° wide opening angle and dual-layer sealing strips. It integrates a handle lock and includes transport retention hooks, giving you added peace of mind during overnight closing or long-distance relocation. It provides shade and heat reduction in summer, and it lets you keep serving food on rainy days. Built with a modular slot structure, the window can be replaced with tempered glass (sold separately), offering flexible use. | Vevor | | Concession Window 60x36 in Aluminum Alloy Frame Service Window, for Food Truck, Up to 85 Degrees Stand Serving | White | Best Buy
