Manufacturers and contractors insurance is now obsolete, but prior to the 1986 revision of the commercial general liability (CGL) policy, this form of insurance was used as a means of providing premises and operations coverage to manufacturers and certain types of contractors, primarily construction and installation contractors.
Today, if an insurer wishes to exclude the products-completed operations hazard, it can do so by attaching the products-completed operations hazard exclusion endorsement. The insured can then purchase separate products and completed operations coverage.
