Peachtree Woodworking Supply ProGrip Straight Edge Clamps Ideal for Cutting Large Sheets of Plywood and Dado Slots (All 3 Clamps 24, 36 and 50 inch)

Excellent quality and strength. Nice to have for longer cuts. Have ripped 1.5 inch eight foot lumber perfectly

I had my doubts about spening that kind of money for something like this, but it was totally worth it. It seems pretty straight, the mechanism looks well made, it's so easy to use. And, it clamps very well. My only complaint might be that you need to disassemble it to clean it when you get it and that was a little difficult for me. Maybe if I were stonger or something it'd be ok, but I'm not. Anyway, get a towel or rag to help hold the end of the thing when you take it apart since the edge is kind of sharp. I've only used the 24 inch one so far, but I'm sure the others are ok too..

Worked as expected. Rails clamped well and held during the cut. Good quality. Expect to have and use for years to come.

I used these to trim solid wood doors in our home. These guides consistently left black marks on the surfaces of the painted surfaces. I was able to scrub off most of the marks with a cleaner. Not sure why it does that. But it's the reason I didn't give it five stars. Overall a great product and easy to use. Some of the competitor products have a very thin felt strip you can attach to the underside of their guides to prevent marks.

Work great
