Construction Features
The Flexmaster U.S.A.® Type 1B is manufactured
to meet the highest quality standards in strength,
permeability and fire resistance required in a
flexible air duct. Tested to UL standard 181,
this Class 1 Air Connector is fabricated with an
acoustically transparent PE inner film, which
allows mid-range sound energy to penetrate the
duct wall.
Duct Fabric
A Polyethylene fabric, mechanically locked to the
duct helix without the use of adhesives.

The Flexmaster U.S.A.® Flex Duct Kits are manufactured to
meet the highest quality standards in strength, permeability
and fire resistance required in a flexible air duct. The Flex
Duct Kits can be fabricated with a variety of different liners,
including acoustical liners, which allow sound energy to
penetrate the duct wall. Tested to UL standard 181, all Flex
Duct Kit assemblies meet the ETL attachment requirements for
flexible duct to sheet metal collars.
Duct Helix
Made from corrosive resistant galvanized steel, the duct helix is
mechanically formed to attach the duct fabric without the use
of adhesives.

Flexmaster U.S.A.® NI-TL
Triple Lock Non-Insulated
Triple Lock Standard Aluminum Duct
The Flexmaster U.S.A.® Triple Lock Aluminum ducting is an all metal flexible duct that is constructed entirely without the
use of adhesives. The Triple Lock mechanical joint makes an air tight seam, while the circumferential corrugations provide
excellent strength and flexibility. Minimum bend radius to center line is one diameter. However, our recommended radius
is 1 ½ diameters in accordance with accepted practice. Triple Lock Aluminum ducting may be easily cut to size and hand
formed into elbows or offsets to suit job conditions without subsequent sagging or droop. Triple Lock has much lower
pressure loss than conventional cloth ducts due to the small but consistent corrugations that provide both strength and
flexibility.

Triple Lock
Standard
Aluminum Duct
The Flexmaster U.S.A.® Triple Lock Aluminum ducting is an all metal flexible duct that is constructed entirely without the
use of adhesives. The Triple Lock mechanical joint makes an air tight seam, while the circumferential corrugations provide
excellent strength and flexibility. Minimum bend radius to center line is one diameter. However, our recommended radius
is 1 ½ diameters in accordance with accepted practice. Triple Lock Aluminum ducting may be easily cut to size and hand
formed into elbows or offsets to suit job conditions without subsequent sagging or droop. Triple Lock has much lower
pressure loss than conventional cloth ducts due to the small but consistent corrugations that provide both strength and
flexibility.
