Seal in odors and cover unsightly dirty dishes, or pack and stack supplies with this black bus box cover. Constructed of durable, sturdy, heavy duty BPA-free polypropylene, the lightweight lid fits standard weight Winco bus tubs (sold separately), and can withstand the bumps and bruises of a busy foodservice kitchen without bending or breaking over time. It snaps on to create a tight seal that prevents odors from escaping or contents from spilling when transported. Bus tubs and dish boxes are stackable with these lids on, so you can use them to store supplies like table linens, banquet chafers, or extra tableware. The NSF-listed black bus tub cover is dishwasher safe, and measures approximately 20-1/4" x 15-1/2".
