This two-pole unit features a 35mm knockout configuration and a 98mm threaded interface, providing a secure mechanical connection for metering socket installations. It is typically installed by licensed electricians working on residential or light commercial meter bases and service entrance equipment. The compact cartridge design supports reliable locking engagement and is suited for environments where tamper resistance and service continuity are required.\u003c\/p\u003e\n\u003cp\u003eThe 1066371 is applied in metering socket assemblies where a spindle lock cartridge is required to secure the meter jaw contacts and maintain a stable electrical connection. The 35mm knockout fits standard meter base cutout dimensions, and the 98mm thread length accommodates typical socket housing depths. This part is appropriate for new installations and direct replacement service work on compatible meter bases.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-pole cartridge configuration for dual-contact metering applications\u003c\/li\u003e\n  \u003cli\u003e35mm knockout diameter matches standard meter base cutout sizing\u003c\/li\u003e\n  \u003cli\u003e98mm threaded interface provides secure engagement depth\u003c\/li\u003e\n  \u003cli\u003eSpindle lock design resists loosening under vibration and thermal cycling\u003c\/li\u003e\n  \u003cli\u003eCompact cartridge form factor simplifies installation and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement cartridge spindle lock for electrical meter bases requiring a 35mm knockout, two-pole configuration with a 98mm threaded interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with applicable NEC requirements and local utility standards.
