Pretty nice part - they are solid brass, really heavy. A bit tough to get the "pads" directly under the spike with such a heavy box!
I thought the wife was going to lose a hand
The only issue I had was the floor was slightly lower under one spike - just enough to cause a buzz that took days to diagnose. I was sure the port was loose inside and would have to disassemble, but in the end a dime under the foot evened things out. No more buzz!
