These look like new old stock, but l was unable to verify that, so I'm listing them as used. Please see the photos for details.Up for sale I have a lot of seven roller casters. While I am not 100% sure of the brand and part number, they look like Rittal PS-4538. Great parts at a great price!
I have included photos to help you make your decision. I
would be happy to answer any questions you may have about this listing. Thank
you for looking.
