The metal chain tethers the cap to the cable or panel so it stays with the assembly during service — no loose covers to track down. ## Fit Check: Does It Match a DB-15 Female? Yes — this cap is listed for use with D-Sub female connectors, and the 15-position count aligns with the standard shell size. It snaps over the connector face and covers the pin cavity area. ## What the Metal Chain Means in Practice The metal chain is the distinguishing feature here — it permanently attaches the cap to the cable bundle or panel via a small ring or loop. In a rack or cabinet where multiple D-Sub ports sit side by side, a tethered cap won't wander off or get swapped onto the wrong connector. Field technicians appreciate not having to dig for a loose cover.","metaTitle":"Molex 1731120109 FCT D-Sub Dust Cap, 15-Position","metaDescription":"Molex 1731120109 FCT 173112 series dust cap for 15-position D-Sub female connectors.
