During COVID days i decided to upgrade my office and built a desk. I used these for legs. They were more hollow than I was expecting but feel like they will hold the weight they are rated forDue to my never having built anything before I had to shim a lot and these worked ok with shims (I did not use the plastic feet included with these)I also did not use the mounting hardware, I used those easy lock inserts so I can remove the legs without heading to drill back into the woodI would recommend these for smaller things and not a very long desk
