Manual Cut-Offs
US Duct’s manual cut-off gates offer the same sliding closure of our automatic gates, but operate and lock with a manual slide and thumb screw. These gates are solid solutions for applications where changing air flow or regulating CFM are done manually.
Manual Full Gates
These are cast aluminum body units with galvanized or SS steel blades that smoothly move in and out of the air stream to fully cut off the air or partially close off the duct so as to balance the system and direct the air. A thumb screw allows the gate to be locked in any position. These gates come with a raw end that will slide into a cut piece of duct. But they can also be fitted with a rolled lip collar or a flange. Available in sizes to 24”.
Manual Half Gates
Like the Full Gates, these are cast aluminum body units with galvanized or SS steel blades that smoothly move in and out of the air stream to fully cut off the air or partially close off the duct so as to balance the system and direct the air. A thumb screw allows the gate to be locked in any position. However these are designed to fit ONTO the duct once a slit for the blade has been cut. Once the unit has been aligned and screwed to the duct, the blade will move in and out of the air stream. Great for retrofitting a system without removing duct. Available in sizes to 18”.
