Excellent Quality — Perfect for My Table Project

Really impressed with these C-channels. They’re well made, solid, and exactly what I needed for my friend’s table project. The quality was excellent and everything arrived exactly as expected. I’d absolutely buy from this seller again and would recommend them to anyone building or reinforcing a tabletop.

The 3 - white oaks shelves (6” x 48” x 1.75”) purchased for the floating shelves that I’m building were excellent quality with no blemishes and or imperfections. I was able to finish these shelves with a natural sealer and a clear satin finish. Looks great!

I would give 6 stars if I could

Exceptional Maple delivered quickly and exactly as ordered. I used it to build a support for kitchen counter. I was able to match my new Maple kitchen cabinets and it's stunning. At age 78, I honestly hope I'm done with building and staining, but if I had to do it again, I would first contact Jeff Mack for the wood. Thank you Jeff.
