Super Anchor 2904K Sidewinder SRL – Heavy-Duty Cable Fall Protection
The Super Anchor 2904K Sidewinder Self-Retracting Lifeline (SRL) provides unmatched fall protection for workers operating on flat roofs, sloped roofs, or vertical overhead positions. This professional-grade safety device is engineered to arrest falls instantly, significantly reducing the risk of injury on the job site. The Sidewinder series is available in three distinct lengths to meet your specific reach requirements: 20' (2904K), 30' (2903K), and 50' (2901K). For those requiring a complete kit that includes an anchor and harness, consider the Super Anchor 3204 Sidewinder Safety Kit.
Sidewinder SRL Design and Industrial Durability
The Sidewinder SRL features a rugged, impact-resistant ABS housing that ensures long-term durability in 2026's harshest environmental conditions. The 3/16" galvanized steel cable offers superior strength and abrasion resistance, making it the ideal choice for both commercial roofing and residential framing. Each unit is supplied with a high-strength steel autolocking carabiner for secure anchorage. At the working end, the device features a 3,600-pound gate-rated impact indicator snap hook that clearly indicates whether the device has been subjected to fall-arrest forces, signaling that the unit must be removed from service.
Rapid Arrest and Field-Proven Performance
With over 15 years of field-proven reliability, the Sidewinder series has earned a reputation for rapid arrest and minimal deceleration distances. The internal braking mechanism is designed to stop a fall within a maximum arresting distance of 42 inches, keeping the worker safe and minimizing impact forces on the body. For ease of use, the housing includes an integrated carry handle and a specialized warning-label package that is resistant to wear and UV degradation, ensuring critical safety instructions remain legible throughout the tool's life.

Super Anchor Sidewinder SRL FAQ
1. Can the Sidewinder be used on a sloped roof?
Yes. The Sidewinder is designed for versatility and can be used effectively on flat roofs, sloped roofs, or in vertical overhead applications. When used on a slope, ensure the SRL is attached to a compatible anchor, such as the Super Anchor 3013-D Anchor.
2. What is an "Impact Indicator" snap hook?
The impact indicator is a safety feature built into the swivel snap hook. If the SRL has successfully arrested a fall, a red band will appear or the hook assembly will show visible deformation. This provides an immediate visual cue during daily inspection that the unit has been "deployed" and must be sent back for service.
3. Can this SRL be repaired if it is damaged?
Yes. One of the primary advantages of the Sidewinder series is that it can be serviced, inspected, and rebuilt at the Super Anchor factory in Monroe. They maintain a complete inventory of spare parts to ensure a quick turnaround and minimize downtime for your crew.
4. Is the cable safe to use around sharp edges?
While the 3/16" galvanized cable is extremely durable, standard SRLs are not typically rated for "Leading Edge" applications where the cable may fray over a sharp corner. If your project involves working near sharp, unprotected edges, we recommend using a specialized Leading Edge SRL.
5. How often does the Sidewinder need to be inspected?
Per OSHA and ANSI standards, the user must perform a visual inspection before every work shift. Additionally, a "competent person" other than the user must perform a documented inspection at least once a year. The units do not have a mandatory "expiration date" as long as they pass these inspections and are serviced when necessary.
6. How do I avoid common mistakes with a cable SRL?
- 1. Smooth Retraction: Never let go of the snap hook and allow the cable to fly back into the housing uncontrollably; this can damage the internal brake and spring. Always walk the cable back in.
- 2. Cleanliness: Avoid getting grease, paint, or excessive dirt on the cable, as this can interfere with the braking mechanism.
- 3. Correct Orientation: Ensure the housing is free to swivel and align with the direction of the worker to prevent the cable from "birdnesting" inside the unit.
