3M Protecta Rebel self-retracting lifeline 6 ft Overview
The 3M Protecta Rebel self-retracting lifeline 6 ft - a genuine Protecta Rebel SRL and 3M 3100400 - is a 6 ft personal SRL and Rebel self-retracting lifeline built to serve as the connecting device in a complete fall-arrest system. It mounts to an overhead anchorage and connects down to the dorsal (back) D-ring of a worker's harness, paying line out and reeling it back as the worker moves so slack stays out of the way. In a fall, the unit locks quickly to arrest the descent and limit free-fall distance. This Protecta Rebel 6 ft is a separate 3M line from the DBI-SALA Nano-Lok family, though both fill the same connecting-device role. See our best self-retracting lifelines guide for how it stacks up.
Safety note: a self-retracting lifeline is only one part of a complete fall-arrest system - it must be paired with a compatible full-body harness (never a body belt for fall arrest) and a rated anchorage. Confirm the ANSI class, capacity, and connector spec on 3M's datasheet before use, and never anchor a non-edge-rated SRL over a sharp or leading edge.
This is a connecting device only. To build a compliant system you also need a full body harness (see our best safety harness guide) and a suitable anchorage. Browse the full self retracting lifelines range and the broader fall protection category to assemble the rest of your kit, including shock-absorbing lanyards (see our best fall protection lanyards guide) where an SRL is not the right tool for the job. See our fall protection equipment guide for how it all fits together.
The 6 ft working length suits applications with a shorter travel radius than the Rebel line's longer 33 ft, 50 ft, and 85 ft versions. As with every SRL, OSHA 1926.502 / 1910.140 and ANSI Z359 require correct anchorage selection, compatible connectors, a pre-use inspection, and a documented rescue plan. WC Safety lists the model, length, and 3M Protecta branding exactly as supplied; verify the rated capacity, ANSI class, and connector hook compatibility on the unit's own label and in 3M's user instructions before each use.
What It Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Overhead tie-off with short travel radius | Strong fit | 6 ft of line suits a compact work area from a single fixed overhead anchor while the SRL keeps slack retracted. |
| General fall arrest from a back D-ring harness | Strong fit | Connects to the dorsal D-ring of a full body harness as the energy-absorbing connecting device; pair with a compatible harness and anchorage. |
| Foot-level or sharp-edge (leading-edge) tie-off | Verify first | This listing does not designate an edge rating. Confirm the class on 3M's datasheet; choose a labeled leading-edge SRL if working over an edge. |
| Longer travel or larger work radius | Step up length | The Rebel line also ships in 33 ft, 50 ft, and 85 ft versions for longer reach from a single anchor. |
| Work positioning or restraint at a fixed point | Limited fit | An SRL is a fall-arrest connecting device, not a positioning device. Use a dedicated positioning lanyard for that task and keep the SRL for arrest. |
Fall protection is life-safety equipment. A personal fall arrest system must limit free fall and arrest forces under OSHA 1926.502 / 1910.140 and ANSI Z359: use a full-body harness (never a body belt for fall arrest) with a compatible shock-absorbing lanyard or self-retracting lifeline and an anchorage rated 5,000 lb per worker (or engineered to a 2:1 safety factor). Inspect every component before each use, immediately retire anything that has arrested a fall or shows damage, and work to a documented rescue plan. Browse fall protection and full-body harnesses.
Pros & Cons
Pros
- Compact 6 ft self-retracting design keeps line slack reeled in to reduce trip and snag hazards
- Locks under fall load to arrest descent and limit free-fall distance
- Connects to the dorsal D-ring of a standard full-body harness
- Part of 3M's established Protecta Rebel SRL line with multiple length options
- Priced as an accessible entry point into the Rebel family
Cons
- Connecting device only — no harness or anchorage is included
- Listing does not state an edge rating; verify before any sharp-edge work
- Exact capacity, ANSI class, and connector spec must be verified on 3M's datasheet
- Must be permanently retired after arresting a single fall
How It Compares
All models below are 3M Protecta Rebel self-retracting lifelines differing only by working length. Choose by your anchorage height and required travel radius, and verify every rated capacity and connector spec on the manufacturer label before use.
| Model | Length | Line | Best for |
|---|---|---|---|
| 3100400 (this page) | 6 ft | Protecta Rebel | Compact work area from a single overhead anchor |
| 3590500 | 33 ft | Protecta Rebel | Mid-range travel radius |
| 3590550 | 50 ft | Protecta Rebel | Extended travel from a fixed anchor |
| 3590641 | 85 ft | Protecta Rebel | Longest reach in the Rebel line |

Frequently Asked Questions
What length is the 3M Protecta 3100400 Rebel SRL?
This listing is the 6 ft version. The Rebel line is also offered in 33 ft, 50 ft, and 85 ft lengths under different part numbers; order the length that matches your anchorage and work radius.
Is the Rebel line the same as the DBI-SALA Nano-Lok?
No. Protecta Rebel and DBI-SALA Nano-Lok are separate 3M self-retracting lifeline lines. Both serve the same connecting-device role in a complete fall-arrest system, but confirm the specific class, capacity, and connector spec for whichever model you choose on 3M's datasheet.
Does this SRL include a harness?
No. It is the self-retracting lifeline only. OSHA requires a complete personal fall-arrest system, so you also need a compliant full body harness and an anchorage. The SRL connects the harness back D-ring to the anchor point.
How does a self-retracting lifeline work?
An SRL pays out and retracts a lifeline as the worker moves, keeping slack minimal. If a fall begins, a speed-sensing brake locks the line to arrest the fall over a short distance. The Rebel is a personal SRL designed to keep tension on the line to reduce dragging and trip hazards.
Is a body belt allowed with this SRL?
No. OSHA 1926.502 and 1910.140 require a full body harness for fall arrest; body belts are prohibited for arresting a fall. Connect this SRL to the dorsal D-ring of a full body harness. See our fall protection range to complete the system.
What anchorage does this SRL need?
Per OSHA, the anchorage for a personal fall-arrest system must support the loads required by the standard, commonly cited as 5,000 lb per attached worker unless engineered by a qualified person to a lower factor. Confirm this Rebel model's specific class and anchorage requirement on 3M's datasheet.
Is the Rebel 3100400 rated for leading-edge or foot-level tie-off?
The listing title does not designate this as an edge-rated SRL, so do not assume it is suitable for foot-level or sharp-edge anchorage. Check 3M's datasheet for the specific class, and choose a purpose-built edge-rated SRL if your work requires it.
Can this SRL be reused after it arrests a fall?
No. OSHA and ANSI Z359 require that any fall arrest component subjected to impact loading be removed from service immediately. Retire and replace the SRL after any fall event, and follow 3M's inspection and service intervals for normal use.
How do I connect the Rebel SRL to my harness?
The lifeline end connects to the harness dorsal (back) D-ring via a compatible connector; the anchor end attaches to a rated overhead anchorage. Confirm the specific connector types on this 3100400 on 3M's datasheet to ensure compatibility with your harness and anchor before deploying.
How should I inspect the SRL before use?
Before each use, check the lifeline for cuts, fraying, or corrosion; verify the line pays out and retracts smoothly and that the brake locks when pulled sharply; and inspect the connectors for cracks, distortion, or gate faults. Remove it from service if any component fails inspection and follow 3M's guidance.
How does the Rebel compare to a shock-absorbing lanyard?
An SRL keeps the line taut and locks quickly, often reducing free-fall distance versus a fixed-length shock-absorbing lanyard, which can help at lower heights. A lanyard may be the value pick where clearance is ample. Compare both in our fall protection lineup and match the device to your clearance and anchorage.
What other lengths does the Rebel line offer?
3M's Protecta Rebel SRL line spans 6 ft, 33 ft, 50 ft, and 85 ft versions, each a distinct part number. Choose the length that matches your anchorage height and work radius, and confirm the connector spec is consistent with your harness before ordering.
