Reliable Manual Locking and High-Tensile Strength
The 4015M is engineered for maximum security, offering a single-direction locking mechanism with 16 kN of tensile strength. This captive-design rope grab must be threaded onto the lifeline to prevent accidental disengagement from the rope during use. The heavy-duty zinc-plated finish is designed to withstand 2026 job site conditions, providing corrosion resistance and dependable performance for construction and roofing professionals. For a complete safety setup, pair this 3-pack with a Super Anchor 5/8" Vertical Lifeline.
Full OSHA and ANSI Compliance
Fully compliant with OSHA 1926:502 and ANSI Z359.1-07, the Super Anchor 4015M meets the rigorous requirements for Type 1 rope grabs. It features a maximum deceleration distance of 24 inches, significantly limiting the forces applied to the body during a fall arrest event. Whether used for fall arrest or as a fall-restraint device to prevent workers from reaching a leading edge, the 4015M is a trusted choice for safety-conscious teams.

Super Anchor 4015M Mechanical Rope Grab FAQ
1. How does the "Squeeze-to-Adjust" mechanism work?
Unlike automatic trailing grabs, the 4015M requires the user to manually squeeze the device to slide it up or down the lifeline. When you release the squeeze, the internal spring-loaded cam maintains its position. In a fall, the cam bites into the rope instantly, stopping the descent.
2. Can I use this rope grab with any 1/2" lifeline?
No. The 4015M is specifically engineered for 5/8" (16mm) diameter lifelines. Using a smaller 1/2" rope will prevent the cam from biting correctly, creating a dangerous slip hazard that violates OSHA safety standards.
3. What does "Captive Attachment" mean for this device?
Captive means the device lacks a hinged gate. It must be threaded onto the rope at one end. While this takes a moment longer to set up, it provides a high level of security because the grab cannot be accidentally removed from the lifeline while in use.
4. Is a shock absorber required with the 4015M?
Yes. To meet 2026 safety standards, a shock-absorbing lanyard or an integrated energy absorber must be used between the rope grab and your harness D-ring to ensure fall forces stay below 1,800 lbs.
5. How do I know if I've installed it upside down?
Each 4015M is stamped with an "Up" arrow. This arrow must always point toward the rooftop anchor. If installed upside down, the grab will slide freely during a fall and fail to lock. Always perform a "tug test" before starting work.
6. Can this be used for horizontal lifeline travel?
The 4015M is designed for vertical or sloped applications. For horizontal travel across a cable or rope system, different tension and hardware requirements apply. Please submit an HLL Quote Request Form above for an engineered horizontal solution.
7. How do I avoid common mistakes with the 4015M?
- 1. Incorrect Orientation: Always verify the "Up" arrow points to the anchor.
- 2. Over-Greasing: Never apply lubricants to the rope-contact area of the cam. This will cause the device to slip.
- 3. Using Damaged Rope: Frayed or "milked" lifelines can affect the grab's ability to lock. Inspect your ropes daily.
