RIVERWELD Hi-lo Welding Gauge Gage Internal Single Purpose Root Gap Checks Root Weld Space and Internal Misalignment Weld Gap Size Weld Height Weld Thickness Marks Inch

This is pretty good and it's way cheaper than the first one I had that look like this

Looks good

Great tool. Very helpful in my trade.

the red plastic locking screw broke within a hour of use and rendered the gauge useless, but i do have other products from river weld and they are better quality than this. I went ahead and ordered the all stainless hi-lo gauge from them and it's not that much more expensive and way more of a bang for your buck

excelente calidad
