Parts Needed

I want to repair a Sliding glass door in my house and need a pair of top rollers.

I'm sending you photos of the one needed.

Could you please tell me if you sell them?

may I buy it from you?

Otherwise, could you tell me where can I buy it?

Thanks in Advance...

Thanks again for your answer to my questions ...

I would not have any problem in using either one of the replacements you advise me to consider, but don't know if they fit in the frame existing in my doors ...

Attached I'm sending you photos of the existing frame for you to tell me which one could be used, if so ... , I would change both doors and will need two pairs

of the one you indicate.

I already measured the top guides, and they have the of dimensions of the 23-222 part you sell ...

Thanks again, hope they would fit, to buy them from you ..
