Midwest 9 Inch Straight Handle Seamer
The Midwest MWT-S9 is a 229mm (9 inch) straight handle seamer for bending and forming siding trim, fascia and flashing material on site. It sits between the compact 5 inch and the full length 15 inch models, which makes it a useful all rounder for metal flashing work. The interchangeable blades and compound lever action are shared across the Midwest seamer range, so the feel and the fold quality are consistent whichever size you pick up.

Frequently Asked Questions
What size flashing can the 9 inch seamer handle?
The 229mm length is a practical middle size for most standard flashing and trim profiles used on Australian roofs. It gives more leverage than the 5 inch model while still being easy to control on moderate length runs. For very long flashing runs you would step up to the 15 inch straight or offset seamer.
Does this seamer come with spare blades?
The seamer is supplied with the blade fitted and the listing does not state a spare blade in the pack. The blades are interchangeable, so replacement and profile blades from the Midwest seamer range fit the same handle. Check the product listing or contact the store for the blade part numbers if you need a specific profile.
What does compound lever action mean?
Compound lever action multiplies the force you apply at the handles, so the seamer folds the metal with less effort than a simple lever tool. That reduces hand fatigue when you are forming a long run of flashing and gives a more consistent fold across the full length of the metal.
