A little on the pricey side, but really sturdy and well made. I needed an odd size set of brackets to fit a shelf in an awkward spot. I wasn't sure I'd find brackets with arms long enough for my needs without using some ugly white hardware-store shelf brackets. These look great, are very heavy duty, and just what I needed. I debated the purchase because of their initial cost, but once I got them I realized their quality warranted the premium price. Overall I'm very happy with them.

Worked Perfectly

They worked perfectly, I use them to hold a hutch inside a trailer to keep it from moving since it was not gonna be mounted against the wall. I use three of the four of these from the frame of the roof for the trailer down to the top of the hutch and they worked excellent
