KwikSafety Double Leg Rattler Lanyard - Internal Shock Absorber

Our review of the KwikSafety Double Leg Rattler finds it best suited for tradespeople who need a compact, reliable fall arrest lanyard for daily use. The single biggest reason to buy is the integrated internal shock absorber that eliminates a bulky external pack while still limiting arresting force, making it easier to move on roofs, ladders and scaffolding. Practical, OSHA compliant, and built with heavy duty snap hooks, this lanyard balances safety and convenience for workers who want a low-profile energy absorber without sacrificing protection.

Key Features

• Internal Shock Absorber: The built-in absorber deploys up to 48 in and limits average arresting force to about 900 lbs to reduce impact on the user.
• Durable Webbing: Made from 100% polyester tubular yellow webbing that resists abrasion and remains flexible for easier handling on the jobsite.
• Triple Snap Hooks: Comes with three self-locking snap hooks tested to a 5,000 lb tensile strength for secure connections to harness D-rings and anchors.
• Fall Indicator Tag: An integrated tag breaks on impact so users can quickly identify when the lanyard must be removed from service after a fall.
• OSHA Compliant: Designed for a wide range of fall protection tasks where OSHA compliance is required, including roofing, inspections and tower work.

Who It's For

The Double Leg Rattler is aimed at roofers, iron and steel workers, linemen and maintenance crews who need a dependable dual-leg connection to stay tied off while moving between anchor points. Its low-profile internal absorber and robust snap hooks suit jobs where bulk and snagging are concerns, such as steep roofs, ladder work and confined areas.

Those who should look elsewhere include users who require a very long deceleration distance or a visible external shock pack for inspection preferences; other systems with different absorber types or longer deployment length may be preferable for specialized rescue or extreme height applications.

Pros & Cons

Pros

• Compact internal absorber reduces bulk while still providing energy dissipation during a fall.

• Clear safety labels and a fall arrest indicator make post-fall inspection straightforward.
