Door guide replacement request.

Hello,

I believe you are showing the inside portion of the 23-114 top roller guide. This guide is normally used on wood doors but can be used with metal doors that use a corner like the 23-407 or 23-409. The track that goes with this top roller would be the 23-509. Review the specifications of both parts and see what you think. Thank you!

You have the wrong track for your type of door guide. Your door guide is the 23-114 and the track that goes with it is the 23-509. 

If you want to use the 21-452 track that you ordered, you'd need the 23-112 spring-loaded top pivot to fit in the 21-174 nylon roll guide that comes with the track. Review both options to determine which setup you'd like to go with.
