No need to change the crimping adjustment when inserting corners in 18 to 26 gauge ducts.
Each quick loading magazines hold up to 175 corners.
Corners are shipped presorted and oriented for direct loading into the magazine.
No need for hand sorting.
Push the ductwork or fitting into the flange guides and the machine automatically does the rest.
