This is the same Tab as SH2 but we have taken it a step further by joining 2 together to make a bracket, this bridge between tabs also makes the combination more than twice as strong as when used individually. And it saves 15 minutes over single tabs every time. If you are a shop, you need every time saver you can get to decrease work backlog and keep making money, and so much better when it is stronger too. These make tab placement accurate, easy, and fast, period. .25" (1/4) HRP&O Steel, sold in pairs.
