Snuggers

I am looking for sluggers for older bifold closet doors. The track is 3/4" x 3/4" and the slide opening is only 3/8". I have included photos of both the double bifold and single one. I will need sluggers to fit both style doors. Thank you for the help. I appreciate the reply but I still can't determine what will fit inside of a track that is only 3/8" wide. Your web site indicated the spring is 3/8" wide which won't allow for any room for the plastic to fit in. Can you advise if you sell any product that will fit into a 3/8" wide track?
