So easy to use. The angle from handle to the jaws really help get the job done.
Standing seam metal roofing! This tool is so versatile. Wish I would of bought them years ago!

Malco S3R
They work great I like the clamping power, the lock takes some getting used to and the angled vs straight seems to be a great choice.

Use them often nice to have
Makes plenum work simple minus the expensive cost of getting them from an Hvac dealer. Good tool to have in hand and they hold up well like the malco name is known for

Overall Malco has some great solid seamers, but like some (not all) of its competitors they seem to put in a pretty hard spring. when you are bending seams for an extended period of time, just the strength of the spring can wear your hand out. I don't quite understand the logic of having such hard Springs installed where the strength needed to bring the seamer back to open position is minimal. One more issue is when trying to squeeze 2 or 3 over bends it becomes pretty hard. The handles should be almost touching when no sheet is inserted. I work with copper. Hopefully it cracks soon so I can weld it back tighter. Other then that, quality is top notch.
