DOUBLE SLIDING CLOSET DOORS

Hey there, thanks for posting! In our experience, there isn't really any specific closet door that would be considered as being a "regular" closet door. Certain doors are simply made with specific types of hardware. 

With that being said, it would be difficult to determine if the 23-070 is compatible with your door. It will depend, entirely, on what they had installed originally; if the 23-070 is identical to your original hardware then there's a good chance these parts will work as a replacement for you.

At this moment, the only information I would be able to confirm, with certainty, is that the 23-070 and 23-270 are compatible with one another.
