New hardware, metal louvre doors from 1968

Thank you for reaching out to us. You are showing the old original Slimfold bi-fold doors. To improve performance of your doors, you will need one 21-001A bottom threaded pivot pin and three 21-007 guide pins. You will need one for the top pivot and two guide pins, one for the top and one for the bottom. I also related other parts you might need on this page. Review the specifications along with the related media guides and see what you think.
