Q: What is the Freund #01110000 Double Welt Iron used for?
A: This tool is used for forming and refining double-lock seams and welted edges in sheet metal. Roofers and metal fabricators use it to create tight, uniform seams on standing seam roofs, flashing, and trim pieces.

Q: What types of metal can I use the Double Welt Iron on?
A: It is suitable for common roofing and architectural metals such as aluminum, zinc, copper, and light-gauge steel, as long as the material is within typical sheet-metal thicknesses used for roofing and flashing.

Q: Is the Double Welt Iron only for use in a shop, or can it be used on the roof as well?
A: You can use it both in the shop and on the roof. It’s designed for field use on standing seams and flashing details, as well as for bench work when pre-forming panels or trim pieces.

Q: Why would I use a Double Welt Iron instead of standard pliers or a hammer?
A: The Double Welt Iron is shaped specifically to match double-lock seam and welt profiles. It provides even pressure and accurate geometry, making it easier to form clean, consistent, and watertight seams without distorting or damaging the metal.
