Miller TurboLite MFL-4 Personal Fall Limiter, 6 ft, Rebar Hook (400 lb) Overview
The Miller TurboLite MFL-4 personal fall limiter is a compact self-retracting connecting device that mounts directly to a harness back D-ring in a personal fall-arrest system. Under OSHA 1926.502 and 1910.140, fall arrest must use a full body harness — never a body belt — connected to a compliant anchorage; this Miller TurboLite MFL-4-Z7 fills the connecting-device role with 6 ft of engineered webbing and a rebar-hook anchor end.
As a 6 ft rebar hook PFL, its distinguishing feature is the connector layout: it has no unit connector and instead mounts straight to the dorsal D-ring, while the lanyard end carries a steel locking rebar hook that captures rebar or structural steel a standard snap hook cannot. Engineered abrasion-resistant webbing runs in an impact-resistant nylon housing with a built-in swivel, a stainless-steel braking system locks within inches, and the unit weighs about 2.9 lb. This locking rebar hook fall limiter is a web PFL and a 400 lb fall limiter rated for up to a 400 lb user.
Like any device in the fall protection category, this is a buyer-intent item to pair with the rest of a system. Match it with a compatible full body harness and a rated anchor point, and confirm anchorage and free-fall limits and the current standard on Honeywell's datasheet. It meets applicable OSHA, ANSI A10.32 and Z359-2007, and CSA standards, but this is the standard TurboLite, not the edge-rated version, so do not run the web over a sharp or leading edge. Any fall limiter that has arrested a fall must be removed from service. Buyers cross-reference this self-retracting lifeline against the other connector configurations and edge-rated options before ordering.
What This TurboLite Rebar-Hook PFL Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Anchoring to rebar or structural steel | Purpose-built | Large-throat locking rebar hook captures members a snap hook cannot. |
| Direct back-D-ring mounting | By design | No unit connector; attaches straight to the dorsal D-ring, staying low-profile. |
| Weight-sensitive / all-day work | Strong | At about 2.9 lb it is far lighter than an overhead cable SRL. |
| Leading-edge / foot-level work | Not this model | Use a TurboLite Edge or other edge-rated device for sharp-edge anchorage. |
| Reuse after a fall event | Not suitable | OSHA requires any fall-arrest component subjected to impact loading be retired. |
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 self-retracting lifeline or shock-absorbing lanyard and an anchorage rated 5,000 lb per worker (or engineered to a 2:1 safety factor). Mount the PFL to the dorsal D-ring, match the device to the anchorage location and edge exposure — this is a standard, not edge-rated, PFL, so keep the web off sharp edges — calculate fall clearance before each use, immediately retire anything that has arrested a fall or shows damage, and work to a documented rescue plan.

Pros & Cons
Pros
- Lanyard-end locking rebar hook for rebar and structural-steel anchoring
- No unit connector — mounts directly to the back D-ring, low-profile
- Light at about 2.9 lb versus a heavy overhead cable SRL
- Stainless-steel braking system locks within inches; built-in swivel
- Engineered abrasion-resistant webbing; 400 lb rated
Cons
- Standard model — not edge-rated; use a TurboLite Edge for leading-edge work
- PFL only; the full body harness and anchorage are sold separately
- Listed to ANSI Z359-2007 — verify the current revision if your program requires it
- Rebar hook is bulkier than a snap hook — choose the MFL-1 if you need a snap hook
How It Compares
This MFL-4 is the rebar-hook, direct-mount configuration in the 6 ft TurboLite line. Weigh it against the alternatives before ordering:
| Model | Unit end | Lanyard end | Best for |
|---|---|---|---|
| MFL-4 (this page) | No connector (direct mount) | Locking rebar hook | Rebar / structural-steel anchoring |
| MFL-1 | Twist-lock carabiner | Locking snap hook | Carabiner-to-D-ring anchoring |
| MFL-2 / MFL-9 | Carabiner / snap hook | Rebar hook / snap hook | Mixed connector needs |
Choose the MFL-4 for a direct-mount rebar hook, the MFL-1 for a twist-lock carabiner and snap hook, or an MFL-2/MFL-9 for other connector mixes. Whichever you pick, complete the system with a full body harness from the fall protection range.

Frequently Asked Questions
What connectors does the MFL-4-Z7 have?
The MFL-4 has no unit connector; the housing is designed to mount directly to the harness back D-ring. On the lanyard end it uses a steel locking rebar hook for anchoring to rebar or structural steel. Sibling models add a unit carabiner (MFL-1, MFL-2) or dual snap hooks (MFL-9). Confirm the rebar hook suits your anchorage before ordering.
How does the MFL-4 mount to the harness?
Because it has no unit connector, the MFL-4 attaches directly to the dorsal (back) D-ring of a compatible full body harness, keeping the device low-profile and close to the body. Follow Honeywell's instructions for the correct direct-mount attachment method for your harness.
What is a rebar hook used for?
The lanyard-end locking rebar hook is a large-throat hook that connects to rebar, structural steel, or other large anchorage members that a standard snap hook cannot capture. Its self-closing, self-locking gate helps prevent roll-out. Always anchor to a point that meets the required strength.
What user weight capacity does the MFL-4 support?
It is rated for up to a 400 lb user, including tools and equipment. Confirm your combined weight falls within the rated capacity and match the rest of your fall-arrest system, including the harness and anchorage, to the same range.
How much does the MFL-4 weigh?
The unit weighs about 2.9 lb (1.32 kg), slightly more than the snap-hook MFL-1 because of the larger steel rebar hook. It is still light enough to wear directly on the back D-ring without the fatigue of a heavy overhead SRL.
How does the braking system work?
The MFL-4 uses a stainless-steel braking system that locks up within inches of a detected fall for low-impact arrest. The short lock-up distance and built-in swivel keep the device responsive while limiting arrest forces on the worker.
What standards does the MFL-4 meet?
Honeywell lists compliance with applicable OSHA, ANSI A10.32 and Z359-2007, and CSA standards. The current personal-fall-limiter standard is ANSI Z359.14, so if your program requires the latest revision, verify the current certification for this part number on Honeywell's datasheet before use.
Can the MFL-4 be used over a leading edge?
This standard TurboLite is not the edge-rated model. For sharp-edge or foot-level anchorage, use a Miller TurboLite Edge or another leading-edge-rated device. Do not run the web over a sharp edge with a non-edge-rated PFL. Browse our self-retracting lifelines for edge-rated options.
Does the MFL-4 include a harness?
No. It is the personal fall limiter only. OSHA requires a complete personal fall-arrest system, so you also need a compatible full body harness and a rated anchorage. The PFL mounts to the harness back D-ring and connects up to the anchor point via the rebar hook.
Is a body belt allowed with the MFL-4?
No. OSHA 1926.502 and 1910.140 require a full body harness for fall arrest; body belts are prohibited for arresting a fall. Mount the PFL to the dorsal D-ring of a full body harness. See our fall protection range to complete the system.
Can the MFL-4 be reused after 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 PFL after any fall event, and follow Honeywell's inspection intervals for normal use.
How should I inspect the MFL-4 before use?
Before each use, check the webbing for cuts, fraying, or chemical damage; verify the web pays out and retracts smoothly and that the brake locks when pulled sharply; inspect the rebar hook gate and lock, the direct-mount attachment, and the swivel; and check the nylon housing for cracks. Remove it from service if any component fails inspection and follow Honeywell's guidance.
