Midwest MWT-SO6 6 in. Offset Hand Seamer

The Midwest Snips MWT-SO6 6 in Offset Hand Seamer is a hand-operated tool designed for bending, forming, and flattening sheet metal during HVAC, ductwork, and general sheet metal fabrication tasks. Its offset jaw design helps improve access when working near edges or obstructions. With a 6 in blade length and throat depth, the seamer supports controlled shaping of metal within its listed capacity ranges. This tool is built for consistent performance with a variety of sheet metals.

Key features:

• Offset jaw design improves access and control when forming sheet metal
• 6 in blade length supports broader surface contact for uniform bends
• Hand-operated construction allows precise control and shaping
• Listed capacity ranges help match tool use to material thickness

• Type: Offset
• Blade length: 6″ (152.4 mm)
• Throat depth: 1-1/4″ (31.8 mm)
• Capacity – Stainless steel: 24 ga.
• Capacity – CR steel: 22 ga.
• Capacity – Aluminum: 20 ga.
• Capacity – Copper: 22 ga.
• Capacity – Galv.: 22 ga.

Q: Why use an offset design instead of a straight seamer?
A: The offset jaw design improves access and visibility when forming or bending sheet metal, especially near edges or obstructions.

Q: What does “throat depth” mean?
A: Throat depth indicates how far into the sheet material the tool can grip when forming bends, which affects where bends can be made relative to the edge.

Q: Why are gauge capacities listed for different metals?
A: Each metal type has differing hardness and thickness properties, so defined gauge capacities help indicate what materials the tool can handle effectively.

Q: What types of projects is this seamer suited for?
A: It is well-suited for HVAC ductwork, sheet metal fabrication, and other tasks that require controlled bending, forming, and flattening of sheet materials.
