Frequently Asked Questions

Sub Total: $0.00

Are all components available on the store?

No. Although we have over 3000 parts available on the store, complexity of other products, special fabrications and our extensive fabrication abilities make it impossible for a complete listing. The store contains the most commonly bought items, HOWEVER, if you need a special dimension, a special ring, a special hood, a special degree PLEASE CALL. 866-562-3828.


What is the difference between Components and K&B Duct?

Largely component parts has worked with sheet metal fabricators or others who have fabricated their own duct but found it more cost effective to order angle rings, smaller elbow, cut-offs etc from Kirk & Blum. K&B Duct provides parts as well, but normally providing ALL of the parts in a continuous system. The clamp together duct, known by the brand, KB Duct, is a fast and easy way for end-users and installers to purchase a total system or to buy parts that can be incorporated with their existing systems or ones that they are fabricating themselves. While K&B Duct is know primarily for the KB Duct, we are also able to fabricate all kind of connection ends.

What is shipping time?

In a word it is FAST. Usually less than four days from the receipt of the order. If you need it faster let us know.


What if I make a mistake in ordering parts I don’t need?

If you are worried about it, give us a call and let us help you look over the order. However, our return policy is 25% restocking when standard products are returned freight pre-paid and in original condition. Parts that have ‘called’ dimensions are not returnable as they are fabricated to your specification.


How is freight calculated?

It is a factor of price and distance shipped. As volume (number and sizes of boxes) also plays a factor into the cost, we will only quote freight on orders under $2000. Larger orders will require closer examination.
