SWISCO - The Replacement Hardware Authority

Meta bi fold doors

A quick learner from USA says:
Dear Customer Service,
I am doing a renovation and do not want to change the metal bifold doors. I am trying to identify the correct replacement parts for National doors, and would like to purchase a complete set (including channel, if available)for each door. I have attached a picture of the pivots, which I am trying to identify (photo 1 and photo 2).
I have already identified the following parts:
Bifold Door bottom Pivot (this would replace photo 3), your 21-046 and Your 21-204

Is there a possibility that you could recommend a complete replacement set, including the channel, which is a little beat up too?

Please send a list of parts so Ican place the order to be delivered by this coming weekend.

Thank you for posting, Leon. Check out our 21-401, 21-402, 21-403, and 21-404. Could you use any of these as a track? If so, you might also want to look at our 21-001 and 21-007 pins, as well as our 21-277 bumper. Let me know what you think.
