Plastic Duct Plugs

[walker]

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,
