Shower door pivot hinge replacement

A quick learner from United States says:
After further investigation, it appears that the top has a metal pin, with the plastic Cap. The top hinge is in good shape.

If the lower pin is intact, all I would need to do is to change the plastic Pin Cap. If that is the case, are your experts thinking that the replacement Cap would probably not be as good as the original, even if it is the same dimensions? i.e. different material and would not last. P/N 21-100 actually looks like it is exactly what is in the top hinge assembly currently.

Or, most likely, your experts know that when I remove the door and look at the lower pin, it will be destroyed, and oh well.

My plan is to identify a replacement door, complete. Then, take the existing one apart and have a look.

Happy New Year

Hi Dave!

It looks like you have an older shower door with Aluminum framing around the glass. Most Shower doors today are the "frame-less" type. I'm not sure if you will be able to find your exact pivots for your door but see if you can find a name off of the door stating who the manufacturer was. If you can find the manufacturer or supplier they may still have parts for your door. 

If not, try the caps you found on the web site to see if they could work for you. I do believe the material should be close to the original pivot. Also, try using a spray lubricant to clear up that corrosion you show in your photo. Worst case scenario, you might need to replace the complete door. Thanks for contacting us!
