How Unistrut Clamps Save Time and Money on Industrial Duct Installations
These Unistrut Clamps are used to attach industrial ductwork (Nordfab, U.S. Duct, Jacobs Tubing, or custom ductwork) to Unistrut or B-Line strut channel and they provide a firm connection that eliminates duct or tubing movement.
The Unistrut Clamp is manufactured:
- To fit ducting with diameters from 3 in. to 24 in. in either galvanized steel or 304 stainless steel
- Bolt and nut are supplied with the unistrut clamp.
Tested by MET Laboratories to hold, without failure, up to 170 lbs for 9 inch diameter duct and up to 850 lbs for 20 inch diameter duct.
- At temperatures ranging between 390° F and 480° F, the zinc-iron alloy layers in the galvanized steel will continue to provide a high level of protection from corrosion. However, there may be some peeling, changes in mechanical properties, and reduction in the corrosion protection. Recommended maximum service temperature is 390° F.
- For 304 SS metal, bluing may occur at temperatures of 800° F and above.
