Good product but don't add over pressure.
Product didn't do what I bought it for but did end up using these to solve a different issue with another set of brackets.

works great
Was creating a "zero" clearance fence for my chop saw out of 2060 aluminum extrusion. Center pieces are 6" long and I used these to hold the center pieces in place while making a 90, 45 and -45 degree cuts. I have 3 of these on each side of the cuts (each piece labeled) loosen the set screws, slide them out of the way, remove the center piece, replace with another set and have accurate cuts. (until I change the blade, at which time I'll need to make new center pieces).

Good quality for a fair price.
Used as a brace on extruded aluminum table legs. Working well thus far.

They are OK, alignment bumps on bottom
They are OK, the downside is some alignment bumps to align with the channel - but you can't place them across without filing them down. The finish is OK.
