The LiftMaster 658200 Coil Cord Edge Connection Kit (20 ft) is a hard‑wired solution for linking a door‑mounted safety sensing edge to a LiftMaster commercial door operator. The coiled cord stretches and retracts as the door travels, maintaining a reliable connection so the operator can detect contact at the bottom edge and initiate a stop or reverse, supporting safe operation on sectional and rolling steel doors. It is commonly used as a replacement part or upgrade when a dependable wired edge connection is preferred over wireless alternatives.
This 20‑foot coiled lead is designed for commercial and industrial applications where a traveling cable is required between the moving door and the operator’s control input. Installers should route and secure the cord to prevent pinch points, ensure adequate slack through the full door cycle, and wire it according to the operator and sensing edge instructions to meet UL 325 safety requirements. Verify compatibility with your specific LiftMaster commercial operator and the type of sensing edge being used before installation.
