Mounted my indicator to this flat back and was pleasantly surprised by how rigid the aluminum feels compared to the plastic ones I've used before. The 4-hole pattern aligned cleanly with my existing bracket, and the stable surface has noticeably improved my setup repeatability.

The machining on this back is clean and the flat surface sits flush without any wobble, which is exactly what my AGD Group 2 dial indicator needed. Mounted it in a few minutes and it holds steady during use.

The 4-hole pattern lined up perfectly with my Group 2 indicator, and it sits totally flat on the surface plate now. Installation took me less than five minutes, and it feels solid enough that I don't worry about it shifting mid-measurement.
