FlexaBoot® Frequently Asked Questions

I’m a mechanical engineer, why would I specify FlexaBoots instead of sheet metal boots?

FlexaBoot provides multiple advantages:

  • FlexaBoots cost approximately 50% less compared to sheet metal boots
  • Flexibility above ceiling – easy to offset over, under, and around obstacles
  • FlexaBoots are acoustically designed and tested - sheet metal boots are not
  • No fibrous materials in the air stream
  • FlexaBoots weigh 9 lbs each - sheet metal boots weigh approximately 47 lbs each
  • All components are U.L classified and made in USA

Have FlexaBoots been acoustically tested?

Yes, read “Test Data” for acoustical testing reports.

I’m a contractor and I can see FlexaBoot submitted as a Value Engineering alternative, will mechanical engineers accept FlexaBoot?

Yes, thousands of FlexaBoots have been accepted and installed through the V.E. process, saving thousands of dollars on numerous projects.

What type of return grille works best with FlexaBoot?

The most economical choice is 24x24 perforated face grille with either a 16” round neck or 10” round neck. Square-to-round adaptors allow FlexaBoot to be used with almost all return grilles with 22x22 and 22x12 necks sizes.

What sizes of FlexaBoots are available?

FlexaBoots are available in 10” and 16” round. The 10” round is typically used with 24x12 face return grilles. The 16” round is typically used with 24x24 face return grilles.

How are FlexaBoots shipped?

Both 16” and 10” FlexaBoots ship two per carton.

How many hangers are required for each FlexaBoot?

One hanger per FlexaBoot. Sheet metal boots typically require at least three hangers per boot.

Can I attach a FlexaBoot to the return grille on the floor and set the entire assembly into ceiling grid?

Yes, FlexaBoot is lightweight and “flexible” – one worker can install FlexaBoot compared to two workers required for sheet metal boots.
