Does anyone know where I can get my hands on those plastic 1" duct plugs that the duct cleaners use. With winter coming I've been drilling a lot of inspection holes and just simply tin taping them up, I'd like to start plugging them with the plastic plugs for a cleaner look. Anyone know I could get my hands on some?
My duct cleaner orders 1000 plugs at a time from Heat Seal Equipment,
