As title says. Good quality, holds the weight well and is protected where the bar rests.
I bought these to replace some spotter arms for my fringe sports 2x3 squat rack after my movers lost one of them and they fit perfectly with exceptional build quality at any price, but especially for this price (compared to R**** Infinity, etc). Added bonus was them being currently in stock and shipping quickly. My previous arms didn't line up flush with the vertical of the rack even after a replacement set was sent, but these Burli's are perfect. I'll be back for future needs!
For those of us with tight spaces for our gym equipment, these are great! They barely squeak in to position when the rack is the open position and best of all they store on the back side of the rack when not in use. Luckily i have not failed on them yet but they will do just fine when i do.
