We believe your guide pins are 1/4" in diameter and the threaded pin is 5/16". Therefore, we suggest replacing all the tracks with new ones. I have pulled up a variety of lengths and they already come with the pivot brackets. Please look at that detailed list on this page. Just a note, for each panel you will need one bottom threaded pivot pin, like our 21-002 as well as three guide pins, like the 21-044, and one bumper per track. |
The info is very helpful. I have (2) tracks : 47 1/2" and 47 5/8".
There appears to be a plastic bushings or fittings at the top and bottom of the door where the pins go through the slot in tthed metal door.
My track appears to ber wider than the one in the picture.
My existing track is 1 3/8" wide, 1/2" tall, and the opening in the track is 7/16"
I am not sure if the size of the track matters, except for the carpeting on the floor
Considering we are changing all the hardware.

I'm afraid that your track is no longer available. I'm suggesting a replacement so you can keep the doors. The 21-404 tracks are 47" long and made to fit in a 48" opening. You would center the track in the opening, so there'd probably be a little space on either side. There is no need for the tracks to go the complete length anyway so it's fine. It won't interfere with the operation of the door, since there's no reason the sliding hardware would ever go that far to either side. If you would feel better filling the total space, you can buy a longer length and cut it down. The nylon bushing that fits in the door to help the pin to slide up and down is our 21-250. |
