Reviews

Rated 5 out of 5 by from Copper welding backer This is a life saver!! It is super easy to use when you need to fill in holes or gaps, just weld directly on the plate and it doesn’t stick to the copper!!

Rated 5 out of 5 by from Another Wonderful Tool These are made from 1/8" copper plates w/ good strong magnets imbedded in them. I had always kept a sheet of copper under the workbench to be cut and used as a welding backer when needed. These are much heavier, easier, reusable, faster and so much more convenient. An awesome investment !
