I bought this to replace the crappy one that came with my DeWalt DW745, whose pivot pin had sheared off during a little mishap. The Delta miter gauge has a little washer at the bottom of the guide that rides in the T-track and keeps the gauge from tipping out. It's a great feature if your saw supports it. Mine doesn't, so I needed to remove it. There's just a Phillips-head screw holding it in but unfortunately, as one of the other reviewers said, it's virtually impossible to remove. I ended up having to drill out the screw. Also, as mentioned by this same other reviewer, I discovered that there were no holes in the miter head for attaching an extension fence, even though the instruction sheet states that there are. So I will have to drill those myself.Once I got these issues sorted out, the miter gauge worked great. It should have been more painless though.
