Exception: An assembly or component part intended to be cut to length or to be tted by the installer is provided when means are furnished for joining any altered part to a companion part or assembly. All fasteners required to complete the assembly shall be p
48、rovided with the product by the manufacturer. Drilling shall not occur unless: a) The drilling operation does not weaken the assembly or penetrate into the ue liner; and b) The size of the required drill bit is specied and the instructions clearly describe the locations to be drilled, such as by the
