Nice when you need stainless
I bought these to hang a stainless steel pot rack from my kitchen ceiling. I used stainless chain with 1/4" thick links to match the hardware--complete overkill, but made for a nice uniform look.My ceiling joists were not where I could use woodscrew-type hooks. Instead I transitioned from these to threaded rod above the ceiling to a 2x4 across the joist tops.Strong, clean, and my wife is happy.
