Yes. The Miller 8174/U is a manual rope grab designed to move up and down a vertical rope lifeline and lock quickly in the event of a fall, providing continuous fall protection as a worker climbs or descends. It has a trailing design that follows the worker for hands-free positioning, and a compact, corrosion-resistant stainless steel body built for long-term durability. It meets or exceeds OSHA 1910.66, 1926.502 and ANSI A10.32, Z359.1 requirements, making it a solid choice for construction, utility, and maintenance work on vertical lifelines.

The Miller 8174/U manual rope grab meets or exceeds OSHA 1910.66 and 1926.502 and ANSI A10.32 and Z359.1 requirements for personal fall arrest systems. It also carries a TAA-compliant designation. These standards cover fall-arrest performance for construction and general-industry work on vertical lifelines.

The Miller 8174/U is designed for use with 5/8" or 3/4" synthetic rope. Miller rope grabs are intended for a 5/8-inch (16 mm) synthetic rope lifeline with a minimum tensile strength of 5,000 lb (22 kN), secured to an anchorage that is independent of the worker's platform. Compatible lifeline lengths include 25 ft (7.6 m), 50 ft (15 m), 75 ft (23 m), and 100 ft (30 m).

The Miller 8174/U manual rope grab has a rated weight capacity of 310 lb. The rope grab itself has a tensile strength of 3,600 lb, and it is meant to be used on a lifeline with a minimum tensile strength of 5,000 lb (22 kN). Always confirm the total user-plus-tools weight falls within the 310 lb rating.

A manual rope grab like the Miller 8174/U attaches to a vertical rope lifeline and slides freely as the worker moves up or down, trailing along for hands-free climbing. In a fall, the device grabs the rope and locks quickly to arrest the descent. The "manual" design means the worker can slide it along the line during normal movement, while the internal cam engages automatically the instant a fall begins. Its stainless steel body includes an O-ring for connecting to the fall-arrest system.

Yes. The Miller 8174/U is built from stainless steel, giving it corrosion-resistant, highly durable hardware suited to wet, outdoor, and corrosive environments. Its compact, lightweight design and stainless construction (with an O-ring) support reliable long-term performance where standard steel components would rust.

The Miller 8174/U is designed for use with a 5/8-inch (16 mm) synthetic rope lifeline that has a minimum tensile strength of 5,000 lb (22 kN). The lifeline must be secured to an anchorage that is independent of the worker's platform. The rope grab also accepts 3/4" rope, and the device itself has a 3,600 lb tensile strength and a 310 lb weight capacity.

The Miller 8174/U Manual Rope Grab (for 5/8" or 3/4" synthetic rope) is available at Industrial Safety Products (industrialsafetyproducts.com) with free shipping. It ships in a silver stainless steel finish, one size, and is a TAA-compliant Miller (Honeywell) fall-protection product.

For durability and corrosion resistance, yes. The Miller 8174/U uses stainless steel construction rather than aluminum or plated steel, so it resists rust and holds up in wet, outdoor, and corrosive conditions over the long term. It stays compact and lightweight while delivering fast lock activation during a fall, and it meets or exceeds OSHA 1910.66, 1926.502 and ANSI A10.32, Z359.1 requirements — a meaningful upgrade for demanding jobsites.
