Midwest 9 Inch Offset Handle Seamer

The Midwest MWTSO9 is a 229mm (9 inch) offset handle seamer for bending and forming siding trim, fascia and flashing material.

Frequently Asked Questions

What makes the offset handle useful?

The offset handle places your hand to the side of the head, so it stays clear of the metal you are folding. That matters when you work flashing against a wall, parapet or fixed surface, because a straight seamer would force your hand into the obstruction or the folded metal.

How does this compare to the 9 inch straight seamer?

The head and blade system are the same family, but the handle position differs. The straight model is better for open bench work and long runs, while this offset model is better for work against walls and in tight spots. Roofers often keep both sizes in the tool box.

What sheet metal can I fold with this seamer?

It folds the sheet metal used in roofing and cladding, including Colorbond and Zincalume flashing, fascia, barge capping and siding trim. Cut the metal to length with snips or shears first, then fold it in short steps for a clean, even line.

What maintenance does an offset seamer need?

Keep the blades clean and dry between jobs, and wipe any metal dust or moisture off the pivot and the handle. A light oil on the moving parts keeps the compound lever action smooth. Store the seamer in a dry toolbox so the blades and grips are ready for the next job, and check the blade for chips or dull edges before heavy work.
