Protecta 3590038 Self-Retracting Lifeline Galvanized Cable with Swivel Snap Hook (50 ft.)
The 3M™ Protecta® Self-Retracting Lifeline (SRL) is an affordable fall prevention solution without sacrificing effectiveness or safety. It is strong yet lightweight and engineered to last. This SRL is developed with the worker in mind, with a stackable housing design, web or steel cable lifeline, and a built-in swiveling anchorage point for extra comfort and convenience. 3M™ Protecta® Self-Retracting Lifelines are available in multiple lifeline lengths as well as SRL, personal SRL, Leading Edge SRL, and Retrieval SRL configurations.
As the worker performs their various tasks, the 3M™ Protecta® Self-Retracting Lifeline (SRL) extends and retracts with them. The lifeline's constant tension prevents slack which can cause dragging, snapping, and trip falls. Should a fall occur, a speed sensing brake system activates, stopping the fall and reducing the forces imposed on the user to safe levels.

Yes — for most overhead tie-off work, a self-retracting lifeline (SRL) like the Protecta 3590038 gives better protection than a traditional shock-absorbing lanyard. The 50 ft galvanized-cable SRL keeps the line under constant tension so there is no slack to snag or trip on, and its speed-sensing brake locks within inches of a fall (versus the several feet of free fall a 6 ft lanyard allows) to keep arrest forces at safe levels. It meets ANSI/ASSP Z359.14-2021 (Class 1), 29 CFR OSHA 1926.502 and 1910.140, supports workers up to 420 lb (190 kg), and uses a lightweight, corrosion-resistant thermoplastic stackable housing built to last on the job. It's an economical yet durable SRL for construction, industrial, and MRO fall protection.
The Protecta 3590038 meets or exceeds ANSI/ASSP Z359.14-2021 and is rated ANSI Class 1, and it complies with OSHA 29 CFR 1926.502 (construction) and 29 CFR 1910.140 (general industry). Z359.14-2021 is the current U.S. standard for self-retracting devices — all SRLs made after August 1, 2023 must conform to it — so this unit reflects the latest fall-protection requirements.
ANSI Class 1 (under ANSI/ASSP Z359.14-2021) means the Protecta 3590038 must be anchored overhead — at or above the wearer's dorsal (back) D-ring — with a maximum allowable free fall of 2 feet and a maximum arrest distance of 42 inches. In short, it is designed for overhead anchorage points, not foot-level tie-off. Its built-in swiveling anchorage loop and carabiner make it easy to connect to an overhead anchor.
The Protecta 3590038 uses a quick-activating, speed-sensing braking system. During normal work the 50 ft galvanized cable extends and retracts freely with the worker while staying under constant tension. If the worker starts to fall, the increase in cable speed trips the internal brake almost instantly, stopping the fall in a short distance and reducing the forces imposed on the body to safe levels — the same principle as a seatbelt's inertia lock.
The Protecta 3590038 has a weight capacity of 420 lb (190 kg), which includes the worker plus tools and equipment. It is rated for a single user (maximum one person) in a single-leg configuration. This capacity is consistent with its ANSI/ASSP Z359.14-2021 certification.
The Protecta 3590038 has a 50 ft (15.2 m) lifeline made of galvanized steel cable, chosen for strength and abrasion resistance in demanding environments. It ends in a self-locking steel swivel snap hook that connects to the worker's harness D-ring, and the swivel reduces cable twist as the worker moves.
No. The Protecta 3590038 is an ANSI Class 1 SRL, meaning it must be anchored overhead (at or above the dorsal D-ring) and is not rated for leading-edge or foot-level (below-D-ring) applications. For sharp-edge or foot-level tie-off you need a leading-edge–rated SRL (ANSI Class 2 / Leading Edge model). 3M's Protecta line also offers Leading Edge SRL configurations for those uses.
The Protecta 3590038 mounts to an overhead anchor point (block-to-anchor) using its built-in swiveling anchorage connector loop and a carabiner made of zinc-plated steel. The 50 ft galvanized cable then connects to the harness back D-ring via a self-locking swivel snap hook. The swiveling anchorage and snap hook let the unit rotate with the worker to prevent cable twist.
The Protecta 3590038 is built for industrial and occupational fall protection in construction, general industry, manufacturing, oil & gas, wind energy, mining, and military MRO. Typical applications include assembly, inspection, maintenance, cleaning, blasting, climbing, and welding. It is intended for trained workplace users only — not for consumer use. Its compact, corrosion-resistant thermoplastic stackable housing and integrated carrying handle make it easy to move between job sites.
All three are the same ANSI Class 1 Protecta galvanized-cable SRL, meeting ANSI/ASSP Z359.14-2021 and OSHA 1926.502/1910.140, rated to 420 lb (190 kg) with a self-locking swivel snap hook. The only functional difference is working reach: the 3590038 has a 50 ft (15.2 m) lifeline versus 33 ft (10.1 m) on the 3590036 and 20 ft (6.1 m) on the 3590034. Choose the 50 ft model when your overhead anchor is far from the work area or you need the widest horizontal working radius; choose a shorter version when a smaller drop is enough and you want a lighter, more compact unit.
The Protecta 3590038 Self-Retracting Lifeline (galvanized cable, 50 ft, swivel snap hook) is available at Industrial Safety Products (industrialsafetyproducts.com) with free shipping. It comes in Protecta's signature red housing. It is the genuine 3M Protecta unit (SKU 3590038 / 3M ID 7100318438), a Class 1 SRL meeting ANSI/ASSP Z359.14-2021.
