PowerBase, Grounding Magnet, 300A @ 60% Duty Cycle, 44 LBS Magnetic Force, On/Off Switch, Machined V Surface, Copper Connector Stud, GM203, Strong Hand Tools

Good magnet for shop use ..

This ground clamp comes in handy and is a great substitute for the usual spring clamp!

Arrived fast and as advertised!

Great product! Highly recommend

Works exactly as described!

I put this grounding base on a Shark 2 dent puller. The weight of the grounding cord would pull the powerbase off the panel. I'm going back to the disk that came with the unit.

I have a Lincoln 140 MP. I saw this item at my local metal shop but saw it for less on Amazon as expected. I had bought a Mag Switch 300 amp from Amazon. That didn't hold well. This was much better. The name Strong Hold is not necessarily true but it did a lot better than the Mah Switch. I used it on the rack of my Grizzly cause I was doing some repairs. It not come off or fall unlike the Mag Switch. The only con I noticed is unlike the clamp, there wire is fed through the handle so there's support for the end connector. It can't be bent if you grab it by the cable. I almost bent mine but caught it on time. I had to make an adapter because it's a 3/8 inch hole end connector. The Lincoln would not fit. I'm going to add a sleeve to support the connection so it won't bend.

Great item,
