These squares are perfect for trimming everything in my shop. I've been using these squares for about a month now and can attest that they are perfect for any job. I use a 2" square to check squareness on articulated wood and I like to use a 6" square to level wood surfaces and all my machines. I didn't think I'd bother with the crate, but since I don't have a tool cabinet yet, they have a dust-free home in the container the squares were shipped in.
