Uneven clearances frequently result from improper installation of frames and frame anchors. One publication, ANSI/SDI 250.11, Recommended Erection Instructions for Steel Frames, will be of assistance regarding the erection and installation of standard steel frames. The Steel Door Institute has many publications which were developed to establish industry standards and assist in specifying as well as installing standard steel doors and frames. Proper installation is extremely important in establishing clearances and preventing a multitude of potential problems. If this clearance is not maintained, interference and hardware misalignment may occur.
All standard steel door and frame manufacturers closely hold tolerances that result in a nominal clearance between the door and frame of 1/8 inch. To ensure proper door and frame function, the clearance between the door and frame must be properly maintained. Modifications made to fire-rated-labeled doors and frames shall be made in compliance with NFPA 80. These types of field installation problems are not intended to be covered in this document and should not be made without first consulting the manufacturer. It should be understood that more complex problems or compound problems could exist which warrant extensive field repairs and modification to products. The suggested method of repairs requires only basic hand tools and relatively little time. It should be understood that most problems encountered are because of inappropriate application of the products and/or improper installation. The intent of this document is to cover field installation problems most commonly experienced with standard steel door and frame installations. The user of this document assumes all responsibility associated with but not limited to product performance and violation of product warranties for any product associated with the installation and suggested repair methods in this document. The Steel Door Institute does not condone or encourage repair methods which would adversely affect product performance or violate and/or void product warranties.
