The production of gas gaps, the core components of the Forward RPCs in the CMS experiment, has reached a mature stage of the production stream. A total of 360 gas gaps, equivalent to 120 RPCs, has been manufactured, tested for quality control, and delivered to CERN in Switzerland and to Pakistan, where the complete Forward RPCs are being assembled. In this paper, the layout of the gas gaps, the production procedures, facilities, and the selection process of the qualified gas gaps are presented.
