This 3/16" thick shock tab is intended to mount to tubing. The tab will allow you to get a fully penetrated weld around the entire tube. The big hole size is for use with 1.5 inch tubing and all shock tabs come with 1/2 hole for shock bolt.
I use these on every bedcage I build. Very strong design. Perfect for mounting a shock to a tube.
