TABLE OF CONTENTS Whether the hollow metal frames are set up and welded or knocked down (KD), if they are not properly stored and installed in metal-framed drywall partitions or masonry openings, problems will arise, if not during actual construction, certainly during the post-construction period. Although the contractor might be diligent in supervising and inspecting the installation of hollow metal doors and frames, by their own forces or by a subcontractor, improper storage or less-than-adequate installation procedures can result in problems that require corrective action. Many of these problem installations can be corrected without total removal of either the door or frame.
