BEAST™ Series 11' SRL Web with Small Hook

BEAST™ Series 11' SRL Web with Small Hook — Overhead Fall Protection for Demanding Job Sites

The BEAST™ Series SRL421311 is an 11-foot self-retracting lifeline (SRL) designed for overhead anchorage applications in construction and industrial environments. Built for trades professionals who require reliable, ANSI-compliant fall protection, it features a robust swivel-top plastic housing in blue, 1-inch polyester webbing, and a 3/4" load indicator snap hook at the attachment end. The unit ships with a 1/2" carabiner included, providing a ready-to-deploy solution for contractors working at height.

Technical Specifications

The BEAST™ Series SRL distinguishes itself with a swivel anchorage eye that reduces torque and tangling during movement, combined with a load indicator hook that provides a visible confirmation of proper engagement — features that add a meaningful layer of jobsite safety over basic snap-hook designs. At 3.52 lbs., it delivers a durable plastic housing construction without the weight penalty of comparable steel-housed units, making it practical for all-day wear.

Key Features & Benefits

Swivel Anchorage Eye

The swivel top at the anchorage end allows the housing to rotate freely as the worker moves, reducing line twist and preventing undue stress on the anchorage connection. This is especially valuable in overhead applications where the worker's direction of travel frequently changes.

3/4" Load Indicator Snap Hook

The load indicator hook provides a visible signal when the hook is properly loaded and engaged, giving workers and supervisors a quick visual confirmation of correct attachment. This reduces the risk of accidental disengagement that can occur with standard snap hooks.

Robust & Durable Plastic Housing

The blue plastic casing is engineered to withstand the rigors of construction environments while keeping overall unit weight to 3.52 lbs. A lighter SRL reduces fatigue over a full shift without sacrificing structural integrity.

1-Inch Polyester Webbing

Polyester webbing offers strong resistance to abrasion and maintains its strength characteristics across a range of environmental conditions encountered on job sites. The 1-inch width provides a minimum breaking strength of 4,500 lbs., well above typical fall arrest load requirements.

1/2" Carabiner Included

The included 1/2" carabiner provides an additional connection option straight out of the box, reducing the need to source compatible hardware separately and allowing faster deployment on site.

ANSI Z359.14-2021 Class 1 Compliance

Meeting or exceeding ANSI Z359.14-2021 Class 1 means this SRL has been validated to current industry standards for self-retracting devices used in overhead anchorage configurations. Contractors can specify this unit with confidence on projects requiring documented compliance.

Common Applications

Overhead Anchorage Fall Protection

Designed specifically as an overhead, Class B SRL, this unit is suited for use where the anchorage point is located directly above the worker, the most common configuration in structural steel, roofing, and elevated platform work.

Construction & Structural Steel Work

The durable housing and high minimum breaking strength make this SRL appropriate for ironworkers and general contractors operating on steel structures where fall hazards are present at multiple elevations.

Roofing Operations

The 11-foot retractable length provides sufficient range of motion for roofing crews working near roof edges or skylights while keeping the lifeline taut and minimizing free-fall distance.

Elevated Platform & Scaffold Work

The swivel top housing and compact design allow workers on elevated platforms or scaffolding to move freely without the lifeline creating a tripping hazard or restricting range of motion.
