I have metal folding doors with no manufactures name on them. I believe they are original to the home built in the 70's. They all work fine but the plastic caps on the track guides are wearing out and i am getting a lot of metal on metal. attached is the piece i would like to buy a dozen of. If i must i would replace the whole piece but only as a last resort. Do you have the part and if not do you know what i am looking for.

Thanks for contacting us! Is this for a closet door? We have a few parts that might match what you have. To begin, please take a look through our Bifold Door Accessories Section and see if you can find a cap to match your own. Let me know if you see anything that will work!

the part 21-111 looks like it to me. Do you think so? If so maybe i will try a couple before I by for all the Closet Doors. I will check the postage also.

Thanks for getting back to us. The 21-111 looks fairly similar, but I can't say for sure without knowing the dimensions of your own hardware. I have a general idea of the size of your own cap based on the pictures, but some of the angles are a bit skewed and I can't make out the exact sizes. That said, compare the dimensions to your own cap and see if it's worth trying out!
