Bi-Fold Door




Hello,
It looks like you have Leigh bifold doors. Unforutnately, there is a limited inventory of Leigh parts, especially the track since Leigh discontinued these doors in the last century. For the four-foot opening, you will need two 21-404 tracks. One for the top and one for the bottom.
For the bottom adjusting pin, see the 21-002. You will need three 21-007 spring-loaded pins for the top pivot and the other two for the top and bottom guide pins. Rubber bumpers and pivot brackets come with the track. You might need two 21-250 nylinders for the 21-002 adjusting pin. No nylinders are needed for the 21-007 pins since they come with nylon tubes.
