I'm restoring a monster of a Victorian chair, which I purchased in very bad condition. The original casters were rusted and broken. I searched all over the internet for new ones that would work, both visually and practically, and did not find the perfect casters until I found these. The shape and depth of the peg was just what I needed, and was not to be found elsewhere. So, just what I needed, at a reasonable cost. I am very pleased!
