Protect your expensive backflow prevention assembly from freezing winter temps with this insulated cover from ArtiGifts. It's designed like a pouch that wraps around your backflow device, made from water-repellent Oxford fabric and industrial aluminum insulation to shield against cold, UV rays, and moisture. The outer dimensions are about 30\ wide x 30\ high x 1.5\ thick—so measure your backflow assembly before buying to ensure a good fit (they recommend at least 3 inches of clearance). It features hook-and-loop fastening tape for a secure seal and two rings for extra attachment options. The pale khaki color blends with many house exteriors. It's a simple, effective way to prevent freeze damage to your irrigation or lawn sprinkler system, saving you from costly repairs. Easy to install and remove as seasons change.
