TrigJig MTS4 Micro Trim Square V2

- Extended length of the straight edge and top rule to 4/12 inches.
- Extended side rule, end to end. Previously 1 inch - 3 inch, it now starts at ½ inch and runs to 3 ½ inch
- New notches feature every ¼ inch exactly to allow for quick stud-off markings. These notches are dead on, so depending on the thickness of your marking implement, pencil, or scribe you can offset the thickness of the mark using the cutaways to reveal and align for increased precision.
- The side ruler now also sits in an anti-wear recess to prevent wear of the laser markings
- Quick mark angle guides are machined into the body on both sides at 60, 45, 30 and 22.5 degrees.
- Every scribe hole is now beautifully chamfered
- Plus they've included an extra ¼ inch scribe notch which was much requested
- There's a handy extra scale on the tip for helping set table router bit depths
- Lastly, combined from the RSA range there’s now a Birds mouth line too


The 45-degree chamfer removed from the corner near the pivot point is handy for using on steel box section, especially where welds may build up in the corners. Or woodworking projects with an internal radius. Allowing the MTS4 to sit tightly into the corner where other trim squares can't for more precise results.
