### ⭐⭐⭐⭐ Not "3/4 X "5/16
*by T***Y on July 17, 2025*

If you are making completely new frames, these will work for you. As stated, they are not "3/4 inch corner blocks. They are '13/16ths. subtract "1 5/8ths from you overall measurements for each run. Also they say they are "5/16ths, again not true. You have to clip the edges off, not hard to do but why? Another issue, you need to clip a small post off the inside to allow the spline to go around the corners. Other than that, they work fine.
