Super Anchor 4020 5/8” 3-Strand Value Lifeline with Snaphook
The Super Anchor 4020 5/8” 3-Strand Value Lifeline is engineered from high-tenacity Poly-Dac rope, delivering an impressive tensile strength of 9,300 lbs. This lifeline is built to withstand the most rigorous industrial safety standards, providing a secure vertical tie-off for residential and commercial contractors. Each rope features a professionally swaged termination with a Z359-rated snap hook and a 3,600-pound gate strength to prevent accidental disengagement. For workers requiring a mobile attachment point on this rope, the Super Anchor 4015-Z Rope Grab is the ideal companion.
High-Strength Poly-Dac Construction
The 4020 Lifeline utilizes a specialized Poly-Dacron blend that offers the perfect balance of strength, UV resistance, and abrasion protection. Available in 25’, 50’, 75’, and 100’ lengths, it provides the reach necessary for high-pitch roofing and exterior facility maintenance. The double-locking snap hook ensures a fast, secure connection to any OSHA-compliant anchor, while the synthetic fibers include integrated UV inhibitors to prevent premature degradation from sun exposure. This lifeline is a critical component for maintaining safety on ladders exceeding 24 feet or on any sloped roof surface.

Essential Safety and Rigging Guidelines
To maximize worker safety and maintain compliance on the job site, follow these mandatory usage tips:
- Individual Use: Each worker must be attached to their own independent lifeline.
- No Knots: Never tie knots in the lifeline rope; knots can reduce the strength of the rope by up to 50%. Use approved limiter knots only if inspected by a competent person.
- Inspection Protocol: Conduct pre-use inspections for frayed fibers, glazing (heat damage), or hardware deformation. Any lifeline subjected to a fall arrest force must be removed from service immediately.

Super Anchor 4020 Value Lifeline FAQ
1. What is Poly-Dac rope and why is it used?
Poly-Dac is a blend of polyester and polypropylene fibers. It is used in the 4020 lifeline because it provides high strength, low stretch, and excellent resistance to moisture and UV light, making it far more durable than standard ropes for outdoor construction use.
2. Can I use a different brand of rope grab with this lifeline?
It is highly recommended to use a rope grab specifically tested for 5/8" 3-strand ropes, such as the Super Anchor 4015-Z. Always verify compatibility in your fall protection plan to ensure the system arrests a fall within the required distances.
3. When should a lifeline be replaced?
Replace the lifeline if you observe excessive "fuzzing," cut strands, chemical stains, or hard spots (which indicate internal heat damage). Furthermore, any lifeline involved in a fall-arrest incident must be retired immediately, even if no visible damage is present.
4. Is this lifeline suitable for horizontal use?
The 4020 is designed primarily as a vertical lifeline. Horizontal lifelines (HLL) are subject to different tension forces and hardware requirements. For horizontal setups, please consult our engineering team for a specific HLL system.
5. Does the rope come with a weight on the end?
Standard 4020 lifelines do not include a counterweight. However, adding a small weight to the bottom of the rope grab can help the rope slide more smoothly as the worker moves up and down the roof or ladder.
6. How do I avoid common mistakes during lifeline use?
- 1. Sharp Edges: Avoid dragging the rope over sharp metal or concrete edges; use edge protectors to prevent the rope from being severed during a fall.
- 2. Snap Hook Connection: Ensure the snap hook is connected to a compatible D-ring or anchor and that the gate is fully closed and locked.
- 3. Storage: Store in a cool, dry place away from direct sunlight and chemicals when not in use to extend the life of the fibers.
