These are new, never installed casters but due to the way these were packed coming from the manufacturer they received some minor nicks in the solid brass wheel. This kit is sold as having minor blemishes in the wheels but will not be noticeable except on close inspection. Kit includes 3 casters, 1-5/8" square mounting sockets, bushings for the socket stems (in case existing hole in piano is larger than the 9/16" new stem - very important to prevent breaking socket). Our Ragland Piano shims are a precise match to the mounting socket. Screws included too. Halfway through the job is NOT the time to find out you need any of these parts!
