Two 1 3/4" steel wheel casters.with three large holes. 4 1/4" to top of post. Surface rust.. I am selling an old collection purchased from a hardware store that had been in business over 100 years. Apparently, they kept everything so what I am selling could be new or used. Smoke and pet free home. I'm happy to combine shipping if items can travel safely together. If I overcharge for shipping, I will refund. Thanks!
