Holds up well!
Size: 4 Pack, Size: 4 Pack
We used these brackets to hold up our snowboards on the wall (as seen in photos, apologies for the bad quality) and they held up very well. The brackets were a little hard to get into the wall, but that may have been the area we put them in. But for the most part the installation was simple, they looked nice, served its function, and are worth the money

Just what I needed.
Size: 6 Pack
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.
