I think we can replace this pin. We have a couple that look very similar, so I already have a few ideas. Before I make any recommendations, though, can you tell me its diameter? That will help us narrow down the list of possible replacements even more. Thank you! |

Thank you! This is a huge help. Knowing that the diameter is 1/4", and that it uses our 21-108, then I think you could have either our 21-058, 21-050, or 21-049. I think one of these might be the guide pin you need for your door. As for how the guide pin functions, I don't think it's meant to move. Many bifold doors have a pin that's completely stationary; that's what you put in first when you install the door, and then all the other pins retract so that you can install each of them. With that in mind, this might be the 21-049. |

The company that made your doors used the 21-050 spring loaded pin for the top guide pin. For the bottom guide pin, they didn't feel it was necessary since the pin locks into the 21-208 nylon guide. I feel both pins should use the spring to help keep the pins locked to the nylon guides, but that's just me. As for The 21-155 locking push nut and 21-157 retainer, we prefer the retainer so you can remove it and reuse it. The 21-155 push nut locks on and can not be reused. |
