Super Anchor 4015 SuperGrab Rope Grab 2-Pack – Deluxe Prussic Knot Fall Protection
The Super Anchor 4015 SuperGrab Rope Grab 2-Pack is a lightweight, non-mechanical rope grab designed as a dependable, all-weather alternative to traditional mechanical devices. Utilizing a specialized prussic knot, the SuperGrab ensures a secure, bi-directional grip on 5/8” vertical lifelines, even in extreme wet or frozen conditions. The knot’s inherent flexibility allows it to expand and contract with the lifeline, minimizing slippage, resisting snags, and preventing damage to delicate roofing surfaces. To complete your system, we recommend pairing this with the Super Anchor 4020 5/8” Lifeline.
This deluxe version features a heavy-duty protective cover that serves as a vital safety indicator: it deforms during a free fall to visualize impact loads, alerting the user to remove the device from service immediately. Looking for a version with a built-in connector? Explore the Super Anchor 4015-V ValueGrab 2-Pack, which features a permanently swaged Z359 snap hook for simplified performance.
Deluxe Protective Cover and Impact Visualization
The 4015 SuperGrab is built for demanding 2026 industrial environments where mechanical grabs often fail due to ice or debris. Its non-metal construction makes it completely weather-resistant and easy to handle without the weight of traditional steel components. With a minimum breaking strength of 5,000 lbs and an average tensile strength of 7,400 lbs, this device provides a 12-inch deceleration distance, significantly reducing impact forces on a worker's body during a fall-arrest event. The bi-directional locking capability makes it an ideal choice for both standard vertical work and advanced reverse-lifeline rigging.

Super Anchor 4015 SuperGrab FAQ
1. Why choose a prussic knot over a mechanical rope grab?
Mechanical rope grabs can sometimes seize or slip when lifelines are covered in ice, mud, or moisture. The 4015 SuperGrab uses a friction-based prussic knot that actually tightens its grip when the rope is wet or frozen, providing superior reliability in extreme roofing environments.
2. How do I know if the SuperGrab has been involved in a fall?
The 4015 model includes a deluxe protective cover. This cover is specifically designed to deform or tear under high-impact loads. If the cover is misshapen or shows visible damage, the device has successfully arrested a fall and must be replaced immediately.
3. Can this rope grab be used for "Reverse Lifeline" rigging?
Yes. One of the greatest benefits of the SuperGrab is its bi-directional locking. You can attach the grab directly to your anchor point and run the lifeline through it, allowing you to adjust the slack from the anchor rather than carrying the weight of the rope on your harness.
4. Does it require a specific type of rope?
The SuperGrab is designed to work specifically with 5/8" (16mm) diameter lifelines, such as the Super Anchor 4020 Lifeline. It is compatible with both 3-strand and 12-strand synthetic ropes.
5. Is a carabiner included in the 2-pack?
No, the 4015 is the "loop-only" version. For a version with a built-in connector, please consider the Super Anchor 4015-V or the mechanical Super Anchor 4015-Z Rope Grab model.
6. Can the prussic knot be retied by the user?
While the prussic knot is a standard climbing knot, Super Anchor recommends that the factory-tied configuration remain intact to ensure the deceleration distances meet ANSI certification. If the knot becomes loose, consult the **4015 Instruction Manual** for proper dressing techniques.
7. How do I avoid common mistakes with the SuperGrab?
- 1. Knot Dressing: Ensure the knot is "dressed" (tight and neat) before use; a loose knot can increase fall distance.
- 2. Sharp Edges: Keep the nylon grab rope away from sharp metal edges that could sever the device during a fall.
- 3. Contaminants: Avoid getting paint, chemicals, or grease on the grab, as this can reduce the friction needed to lock onto the lifeline.
