Ideal for reducing diameter of round duct, sheet metal pipe, and downspouts for insertion into other pipes
Five blades make uniform crimps on sheet metal up to 20 gauge
Recommended for light or heavy piping -- furnace, smoke, wall stacks, air ducts, water heater vent pipes, and downspouts
Crimps up to 1-5/8" back from end for good overlap connection
Heat treated blades for longer wear, hardened pivot bolt for durability, and vinyl grips for comfort
For natural indraw on metal, always start with the three blades on top.
