After remodeling, we are closing in an 125" wide by 34" deep area for a closet, and we'd like to use a sliding bypass closet door system. We were thinking of making the opening around 9' wide. What are the pros and cons of going with 3 vs. 4 doors? Also, we want to purchase hardware that will last, probably with a bottom track, and we want the doors to operate smoothly, quietly, and for a very long time! (smile!) Do you have any brand or style recommendations? How many rails should we use, and is it necessary to purchase the total length across, or can two rails go end to end? What about doors...the closet is going to be used for clothing...what is the best style of door to go with? We would appreciate any help you can give us. Thank you very much!
