Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose the 3 in. jaw for flashing and trim work where tighter control is needed; step up to the 6 in. model for long seams and the offset 3 in. for overhead flashing. Use the 1/4 in. depth graduations to repeat consistent bend depths across a run. Keep the hinge pivot clean so the compound leverage stays smooth.
Sheet metal edges are sharp—wear cut-resistant gloves and eye protection when bending or handling metal.
Add the Malco 3 in. Hand Seamer to your toolkit for precise, powerful sheet metal bends on site.
