I ve used this kit myself.
Convert regular door to pocket door.
Cut it back to the middle of the next available stud and to a height corresponding to the top of the door header.
Trim any added door length when converting your hinged door to a barn door you may or may not need to adjust the length of the door to ensure that it slides smoothly on the railing and ground track without scraping across the floor.
To do this measure the door lengthwise and score a line across the bottom.
Using a drywall saw and utility knife remove drywall from the wall inside the closet to accommodate the.
Measure the width of the door you are going to install as a pocket door with a tape measure.
This means taking down the old swinging door removing the jamb and disassembling the wall framing.
Yes the typical pocket door kit is just the rollers and half studs and you re expected to use a standard door slab.
You have to open up the wall and cut out the old studs to make room to use the metal half thick studs but it was actually pretty easy and very high quality rollers.
Step 2 move door to the fully closed position and remove it from the upper track by pushing the bottom of the door out then lifting up until the rollers detach from the metal track at the top.
Step 2 remove the drywall from one side of the wall to uncover enough space for the door pocket.
