A fair alternative to a full-on power rack and allows you to do many exercises with adjustable safeties. Will be getting these to do some heavier squats and for added safety with my bench press.
Not a super-bargain but if you are in the market for a pair of squat stands it is the cheapest I could find and they seem quite decent. I have no idea of the load rating but I am guessing they take around 200kg based on similar products I've seen.
Certainly safer than using a pair of saw horses!
Hopefully not easy to knock over or to spin one slightly, hard to put it down again if they aren't lined up with each other.
