More about Clamp Together Duct
The clamp together duct system is a full line of duct and components. All parts are of standard sheet metal construction with a rolled lip applied to the each end of the component. An all-stainless over-center locking clamp is used to encompass the rolled lips, pull them together and then securely join them. Adapters enable connection to virtually any machine or existing duct.
The lifetime guaranteed clamp is fitted with a ‘winged- O-ring’ gasket made or N-butyl rubber. The gasket is designed to fully encompass the entirety of the rolled lips including the area formed by the 'v' between the rolled lips. Other gasket material is available. *
Duct and Adjustability:
The clamp together straight duct is a nominal 5’ length. Adjustable sleeves and adjustable components enable the installer to quickly make odd lengths and to adjust for a proper fit. To utilize this feature, a cut piece of pipe is slid into the sleeve or fitting and secured with an O-ring and standard clamp. All fittings (elbows, branches- any part with a collar) will receive a cut piece of pipe. The O-ring, around the duct, allow the duct to clamp to the sleeve and secures the seal around the duct. (See adjustability)
Material Duct and Components are available in galvanized, stainless (304-316) as a standard. .
Duct Standard Gauges for the duct are 26 ga for 3”, 24 ga for 4-6”, 22 ga for 7-12” and 20 ga for sizes 13-22”.
Elbows are typically one gauge heavier than standard duct gauge.
All components (reducers, branches,etc) are of 18 ga material.
Carbon steel and galvaneel are available as an option.
Viton, Gore-tex, Red Silicone Rubber, Asbestos gaskets and O-ring material are also available.
All duct can be provided in standard configuration in one ga heavier. (24 in 22 , 22 in 20 and 20 in 18)
Rolled lips can be applied to gauges upto 10 ga by applying a rolled lip collar to fully welded duct and components.
Heavy tubed elbows are available.
The rolled lip on the duct and fittings act as a stiffing ring and therefore allow the product to withstand much higher pressures than normally associated with spiral or other rolled duct. The duct is typically installed with confidence in pressure applications up to 40” negative water column pressure. Higher pressures guarantees are available. To obtain this simply call K&B.
