Roller Door Guide

I am in the process of having a hollow core pocket door replaced with a solid core birch veneer pocket door. The replacement door will go in a doorway between a water closet that contains a shower and toilet and the rest of the bathroom. I am replacing the hollow core pocket door because it does not maintain alignment with the lock. I had the same experience with a another pocket door in my home and the replacement solid core door seems to work. Now for the question. I am looking at one of your products, specifically, Pocket Door Roller Product Code: 23-049. It looks as though this will certainly support the weight of the pocket door. I expect to require two of these devices.
Now, if I order the part listed above, will I receive all screws etc. required to attach it to the new door???? If not, what must I order in addition?

There is nothing special about the screws. They are standard #8 screws. I would definitely recommend long screws for the extra weight and pre-drilling to prevent splitting.
