Flexmaster Triple Lock product 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 circum-ferential corrugations provide excellent strength and flexibility.

Minimum bend radius to center line is one diameter. However, our recommended radius is 1.5 diameters in accordance with accepted practice. Triple Lock stainless steel ducting may be easily cut to size and hand formed into elbows or offsets to suit job conditions without sub-sequent sagging or droop.

Triple Lock has much lower pres-sure loss than conventional cloth ducts due to the small but consistent corrugations that provide both strength and flex-ibility.

Access Doors

High Pressure Access Door For Sheet MetalThe Inspector Series SDSM

Low Leakage • Quick Installation • Safe Entry and Exit

Flexmaster's - THE INSPECTOR SERIES - SPIN DOOR is manufactured with heavy gauge galvanized steel to meet the highest quality standards required in a high pressure access door. This insulated and gasketed

access door is designed for application in a low to high-pressure HVAC air distribution system. THE INSPECTOR SERIES - SPIN DOOR unique round con-

struction provides for a quick installation as its outer frame is spun into the sheet metal duct and then the self sealing inner door is put into place and

locked by turning the pre-installed latches. The outer SPIN DOOR frame is made of heavy gauge galvanized steel, rolled and double hemmed. The inner door is made of

heavy gauge galvanized steel, rolled and triple hemmed. When the outer SPIN DOOR frame is properly installed and sealed for the specified operating pressure the leakage rate is extremely low. No raw edges are exposed and therefore a safe entry and exit is insured.

THE INSPECTOR SERIES - TAB DOOR is manufactured with heavy gauge galvanized steel to meet the highest quality standards required in a low-pressure HVAC access door. THE INSPECTOR SERIES - TAB DOOR’S strong frame construction provides for a solid installation as its outer frame tabs are formed around the sheet metal duct and then the self sealing inner door is put into place and locked by turning the pre-installed custom latches. The outer TAB DOOR frame is 22 gauge, galvanized steel, formed, notched and hemmed. The double sided insu-lated inner door is constructed of 24 gauge galvanized steel.

Flexmaster Duct Material - Straight Run Friction Loss

Flexmaster Duct Material - 90° Bend Friction Loss

The data presented herein is based on reliable laboratory test. For all sizes the test bend was formed around a template of the same diameter as the duct resulting in a Radius to Diameter ratio of 1. The data has not been extrapolated for other bend ratios but must be considered when comparing values arrived at different R/D ratios.

By its very nature, flexible duct presents variations not present in the measurement of friction loss in rigid pipe. Variations exist between the test procedure and actual field installations and FLEXMASTER U.S.A., INC. assumes no responsibility for performance characteristics resulting from conditions which differ from those used in laboratory tests.
