Dorbin has a minimum order requirement. Orders smaller than the required minimum have a longer lead time as we need to consolidate onto a "stock" order. If you need a faster lead time, simply exceed the minimum order amount.
Dorbin has put into place extreme price increases and their material has become exceptionally expense and strongly urge you to consider Reese or Pemko as alternates.
