Hi there,

I can't seem to find replacement pivots for an old steel mirror bi-folding closet. The base is 7/16 but my track opening is 3/8, which means the nylon has to be somewhat smaller.

Hello,

I don't recognize your bifold pin right off the bat but if we could see your door track, it may help us locate the correct guide part for your repair. Thank you.

When Stanley took over the Acme company, they completely changed the track and nylon guide. The new door track looks like the 21-450, which uses the 21-174 nylon roller guide. The pins are the 23-112 and 23-113. We show a similar spring top guide, our 23-121, but the top nylon cap is 7/16". We do have a 3/8" top nylon cap that fits on a 1/4" pin, the 21-100. Look over these parts to confirm the best replacement parts for your repair.
