Prime-Line N 6789 Bi-Fold Door Guide Caps – 1/4" Inside X 1/2" X 3/8" Plastic – 25-Pack – Replacement Caps For Smooth Bi-Fold Door Operation

About This Product

If your bi-fold doors are catching, dragging, or jumping off track, chances are the guide caps on top of the guide rods are worn out or missing.

Each cap has an inside diameter of 1/4 inch, an outside cap diameter of 3/8 inch, and a rim diameter of 1/2 inch – those are the key measurements to match your existing setup.

You get 25 caps in one pack, which is way more than you need for a single door – but great if you have multiple bi-fold doors, or you just want spares.
Simple fix that makes a big difference in how your doors glide.
