Butt Weld Clamps & Backers Kit is rated 4.5 out of 5 by 4.
Rated 3 out of 5 by from Butt weld clamps Clamps are handy to have around but screws are a bit on the short side,otherwise we're what I expected.The copper backers are a good thing as well but magnets are not strong enough an found them to loose grip from panel and fall off.The first backers that I got would not even hold their own wait to the panel and had to be replaced.

About Butt Weld Clamps & Backers Kit

The 4 butt-weld clamps align panels edge-to-edge and surface-to-surface, with the appropriate 0.040" gap that helps you produce clean welds with full penetration, minimal grinding. Use a magnetic copper welding backer (4" and 8" included) as a hands-free backing support when butt-welding and welding holes in sheet metal or whenever an open area needs to be bridged with a weld; prevents warping and burn-thru. Welding material will not stick to the copper plate.
