Searching for closet door hardware that allows you to lower the door

A quick learner says:

I had carpet and now have refinished the hardwood floors that was underneath. It looks great. The closet door hardware is probably 70 years old and the 2 separate old floor guides already sat on an ugly extra little piece of wood about 5.8' thick which they had carpeted over.

 Now there is going to be a gap at the bottom under the doors, and I will still have to use a piece of wood under a new floor guide. 

Do I need to install some wood under the tracks at the top? Or is there a new hardware set that has top runners that allows the doors to be lowered about 5/8"? I learn how to do stuff with online videos. Not finding one to help with this. Thanks. Jean.

Thanks for reaching out to us! I just recently installed new closet doors at my son's house. He also removed the carpet to expose the hardwood flooring. I actually took a piece of wood and stained it to match the existing flooring. However, with that being said, lowering the top track with a piece of wood the size you need is an idea I didn't think of but it could be a major job. I recommend you take a look at the different types of floor guides we've related on this page along with the 23-221 riser. Look over the specifications and see if one of these could work for your closet door.
