Tape cross tabs may be used instead of staples when sealing seams and joints. Which statement best describes this option?

• A. Tape cross tabs may be used
• B. Criss tabs must be used exclusively
• C. Glue should be used instead of tapes
• D. Seams should be left unsealed

Answer: (A)

Sealing seams and joints on ductwork can be done with either mechanical fasteners or sealing materials. Using tape cross tabs as an alternative to staples provides an effective seal along the seam without puncturing the metal. This method helps prevent air leaks and can simplify installation, especially on certain duct configurations. So, saying that tape cross tabs may be used describes an acceptable substitute for staples when sealing seams and joints. Relying on glue instead of tapes isn’t the standard practice for duct sealing, and leaving seams unsealed would clearly lead to leaks.
