Yes. The Miller MML-OGC1-02/100FT MightyLite+ is a lightweight, compact overhead self-retracting lifeline (SRL) built for construction, utilities, and manufacturing. It meets or exceeds ANSI/ASSP Z359.14-2021 Class 1 and OSHA requirements, supports up to 420 lb (190.5 kg) per OSHA (310 lb / 141 kg under ANSI/CSA), and its quick-activating inertia brakes limit a free fall to less than 2 ft. A 100 ft galvanized steel cable, corrosion-resistant aluminum and stainless steel housing, and improved UV-resistant labeling make it durable for daily jobsite use. As a Class 1 device it is intended for anchorage overhead (at or above the dorsal D-ring), not for foot-level or leading-edge use.

The Miller MightyLite+ MML-OGC1-02 meets or exceeds ANSI/ASSP Z359.14-2021 Class 1 and complies with OSHA requirements for self-retracting devices. The Class 1 designation identifies an SRL intended for overhead anchorage (at or above the user's back D-ring), as opposed to Class 2 units approved for foot-level anchorage and leading-edge use. It is rated for up to 420 lb (190.5 kg) under OSHA, and up to 310 lb (141 kg) under ANSI/ASSP Z359.14-2021 and CSA.

The Miller MightyLite+ MML-OGC1-02 supports up to 420 lb (190.5 kg) under OSHA — the combined weight of the worker plus tools and equipment. Under ANSI/ASSP Z359.14-2021 and CSA, the rated capacity is up to 310 lb (141 kg). Either way, its elevated capacity lets a wide range of workers use a single Class 1 device.

The Miller MightyLite+ MML-OGC1-02 limits a free fall to less than 2 ft. Its quick-activating inertia brakes sense sudden movement and lock almost instantly, arresting a fall in a very short distance and reducing the forces on the worker. This fast-locking behavior is part of what qualifies it as an ANSI/ASSP Z359.14-2021 Class 1 device.

The Miller MightyLite+ MML-OGC1-02 ends in a steel swivel load indicator snap hook. The swivel lets the hook rotate freely so the galvanized cable does not twist, and the load indicator is a built-in visual tell-tale: if the SRL has arrested a fall, the indicator deploys or shows a marker so an inspector can immediately see the unit was shock-loaded and must be removed from service. On the harness end it uses a steel carabiner as the connector.

The Miller MightyLite+ MML-OGC1-02 is engineered to be lightweight and compact so it is easy to carry, install overhead, or permanently mount for repeat use. An integral swivel reduces lifeline twisting for smoother operation, and a narrow payout port limits the intrusion of foreign debris that can foul the mechanism. The 100 ft galvanized cable with corrosion-resistant aluminum and stainless steel housing keeps weight down while extending service life.

No. The Miller MightyLite+ MML-OGC1-02 is designed so that no annual factory recertification is required, which lowers long-term maintenance costs and keeps the device on the job instead of being shipped away periodically. Users still perform routine pre-use inspections and follow the manufacturer's inspection schedule; the UV- and scratch-resistant labeling even provides space to record inspection dates.

No. The Miller MightyLite+ MML-OGC1-02 is an ANSI/ASSP Z359.14-2021 Class 1 device, meaning it must be anchored overhead (at or above the dorsal D-ring) and is not rated for foot-level anchorage or for a lifeline running over a sharp leading edge. For those applications you need a Class 2, leading-edge–rated device. Choose the MML-OGC1-02 when a proper overhead anchor point is available.

This SKU, the Miller MML-OGC1-02/100FT, is the 100 ft version with a galvanized steel cable lifeline. The MightyLite+ MML-OGC1-02 family is offered in 20, 30, 50, 100, and 130 ft lengths, all with a Silver finish. The 100 ft reach suits taller structures and larger work areas, and the galvanized steel cable plus corrosion-resistant aluminum and stainless steel housing is built to hold up in demanding industrial environments.

Yes. The Miller MightyLite+ MML-OGC1-02 is listed as TAA (Trade Agreements Act) compliant, which matters for government and federally funded procurement. Its country of origin is Mexico, and it ships boxed, one per case, in a Silver finish. It is part of Miller's redesigned PLUS family and aligns visually with current Honeywell Miller harnesses for mix-and-match protection.

The Miller MightyLite+ MML-OGC1-02/100FT (100 ft, galvanized steel cable, steel swivel load indicator snap hook) is available from Industrial Safety Products (industrialsafetyproducts.com) with free shipping. It is the current replacement for the discontinued RL100G-Z7/100FT and carries the up-to-date ANSI/ASSP Z359.14-2021 Class 1 rating with a capacity of up to 420 lb per OSHA (310 lb under ANSI/CSA), so it is the modern equivalent for anyone who previously used that unit.
