ABSTRACT:
This disclosure relates to an improved metal duct drive bending tool. The improved metal duct drive bending tool of this disclosure is a portable metal frame type apparatus which uses the pivoting action between two pivotable members of the frame, one of which has teeth, to form a drive at the end of a metal duct that is inserted into a pocket within the frame apparatus between the two pivotable members. The improved metal duct drive bending tool uses the teeth on one of the pivotable members to permit the insertion of various widths of metal duct end portions to be bent.
