Dear Sir or Madam,

We have one of our rental units using the attached roller on our bifold doors - Patent 3261129 with one part being 4023. We are presently looking for this piece as we have several of our units that require replacement. Can you advise if you have this part available. Looked at your site and see something similar but not exact. If you could be of assistance please advise accordingly.
