BEAST™ Series 20' SRL Galvanized Cable with Small Hook

BEAST™ Series 20' SRL Galvanized Cable with Small Hook — Reliable Overhead Fall Protection for Demanding Job Sites

The BEAST™ Series 20 ft. Self-Retracting Lifeline (SRL) is a Class B, overhead-rated fall arrest device engineered for contractors and trades professionals working at height. Built around a 3/16" galvanized steel wire rope housed in a swivel-top blue composite shell, it delivers dependable retraction and arrest performance across a wide range of structural and industrial applications. The unit ships complete with a 3/4" load indicator snap hook, a 1/2" carabiner, and a 20' tagline, providing everything needed for immediate deployment. It conforms to ANSI Z359.14-2021 Class 1, meeting the current industry standard for self-retracting devices.

Technical Specifications

Unlike basic SRL units that ship without anchorage hardware, the BEAST™ SRL611311 includes both a 1/2" carabiner and a 20' tagline, reducing the need for supplemental purchases before a crew can go to work. The swivel anchorage eye at the top and the swivel snap hook at the attachment end both rotate independently, minimizing cable twist and torque on the lifeline during movement. With a 3,000 lb. minimum breaking strength and ANSI Z359.14-2021 Class 1 certification, this unit meets current regulatory requirements without requiring an upgrade to a heavier or more expensive device.

Key Features & Benefits

Swivel Top Composite Housing

The blue composite housing is robust and durable, resisting impact and environmental exposure on active job sites. The swivel anchorage eye at the top allows the unit to rotate freely at the anchor point, preventing cable twist as the worker moves.

Load Indicator Snap Hook

The 3/4" swivel steel snap hook features a built-in load indicator, giving workers and supervisors a visible confirmation that the hook is properly loaded and engaged. Gate strength is rated at 3,600 lbs., providing a secure connection at the harness attachment point.

Galvanized Steel Wire Rope

The 3/16" galvanized steel cable offers corrosion resistance suited to outdoor and high-humidity environments. Galvanized construction extends service life compared to uncoated cable in conditions where moisture, concrete dust, or chemical exposure is common.

ANSI Z359.14-2021 Class 1 Compliance

This SRL meets or exceeds ANSI Z359.14-2021 Class 1, the current standard governing self-retracting devices. Compliance ensures the unit is acceptable for use on federally regulated job sites and satisfies most general contractor safety program requirements.

Complete Kit — Carabiner and Tagline Included

The package includes a 1/2" carabiner and a 20 ft. tagline, so the unit is ready to rig without sourcing additional hardware. This reduces setup time and eliminates the risk of mismatched components.

Wide User Capacity Range

Rated for users from 130 to 310 lbs. (including tools and gear), the BEAST™ SRL accommodates a broad range of workers without requiring a separate heavy-capacity unit for most crews.

Common Applications

Structural Steel Erection

Overhead-rated Class B SRLs are designed for use directly above the worker, making them well suited for ironworkers and structural steel crews connecting beams and columns at elevation.

Roofing and Roof-Level Work

The 20 ft. cable provides sufficient range of motion for workers moving across roof decks while remaining connected to an overhead anchor or roof anchor system.

Concrete Formwork and Decking

The galvanized cable resists the alkaline and abrasive environment of concrete pours and formwork operations where uncoated hardware degrades quickly.

General Construction at Height

The wide 130–310 lb. user capacity and included anchorage hardware make this unit a practical general-purpose SRL for mixed crews on commercial and industrial construction projects.

Maintenance and Inspection Work

The self-retracting mechanism keeps slack out of the lifeline, reducing trip hazards for maintenance technicians working on elevated platforms, catwalks, or mezzanines.
