kitchenratt says:

Awesome video!! I’ve done commercial refrigeration for almost 30 years…. I’ve always been fascinated with tin knocking..I’d love to learn more.

Frank FB says:

This was done very well!

LDoctorKC says:

Awesome presentation. Question: I have a home built in 1986 and has fiberglass ducts with 8” insulated tubes to vents. After all these years I’m concerned about the health consequences of this material. Curious your thoughts or if you have any discussions with fiberglass ducts and proper servicing. My furnace is a 95% efficient gas. Thanks so much Craig.

Dustin says:

Question: If one is planning to install several take-off collars is there still benefit from cross breaking?

Dexal says:

Never heard of a pocket break before. I need to get me one of those!

Sheet Metal Shop Guy says:

This is great for on the fly jobs. But if you're gona use s slip why not save the trouble of doing a recessed cap?

Bedbugs and cockroaches says:

I can't find the hand brake you are using. Can you send me a link? Thank you.

LugNuts says:

Excellent video. Thanks.

Martin P says:

Thumbs Way Up!

A M says:

Great video. I like how you demonstrated the various backing (grass, carpet, cardboard) for the pocket brake. I did not know of the Pocket Brake. Nice tool. I am particularly interested in your duct making videos. Thank you for sharing.

Ramit says:

It's a nice skill to have but I found that charging the customer for a prefabbed plenum saves a lot of time. Often I modify a prefabbed plenum to meet my needs.

Sean Holly says:

I am so glad for this man. Great videos.
