The type of door that requires that the frame be installed before the drywall is a:

• A. bifold
• B. double hung
• C. pocket
• D. hollow metal

Answer: (C)

Pocket doors are designed to slide into a concealed cavity inside the wall, so the door frame and track must be installed while the wall is still open and before the drywall goes up. That pocket needs to be formed by the wall framing, and once drywall is installed, there’s no access to create or fit the pocket properly. Installing the frame beforehand ensures the cavity is correctly sized and the door can slide fully into the wall without cutting through finished drywall. Other door types don’t rely on a built-in wall pocket, so their frames aren’t constrained to be in place before drywall.
