Definition
Replacing one full horizontal section of the door — hinges, struts, and all — when a section is creased, cracked, or rusted beyond a cosmetic fix. Because each section carries load and pivots against its neighbors, a compromised section stresses the whole assembly and can fold under spring tension. Availability is the deciding factor: manufacturers retire designs, and a section for a fifteen-year-old door may simply not exist. When two or more sections are gone, full replacement usually wins the math.
