MSA Workman Tie Back SRL — Twin-Leg Personal Fall Limiter, 7.5 ft, 10125272

The twin-leg tie back SRL — MSA Workman Personal Fall Limiter

A tie back srl lets you anchor straight to a structure instead of carrying a separate anchor connector, and the MSA Workman Twin-Leg Tie-Back Personal Fall Limiter does exactly that: its retractable legs wrap around a column or beam and clip back to the device. With two legs it gives 100% tie-off — keep one connected while you move the other — making it a direct alternative to a twin-leg shock-absorbing lanyard, with the shorter fall distance of a self-retracting device. It runs a 7.5 ft line and uses MSA's patent-pending ARCA harness connection, where you simply insert your dorsal D-ring into a slot to attach.

Shoppers searching a twin leg srl, a tie back fall limiter, or a self retracting device land here; as a twin leg personal fall limiter it is built for moving across large structures. Match it to your harness and structure, covered below.

Pros & cons

Specifications

What the Workman Tie-Back is for

Moving across large structures — steel erection, towers, and structural work — where you tie back to columns and beams and need continuous connection. It sits in the self-retracting lifelines collection, is the connector in the ABC system explained in the fall protection equipment guide and the ABCDs of fall protection, and applies wherever a fall hazard triggers the rules in when is fall protection required.

Building the system around the PFL

Attach the ARCA connection to the dorsal D-ring of a harness from the full body harnesses collection — ranked in the best safety harness guide — and tie the legs back to the structure or to anchors from the anchor points collection, sized to the anchor strength requirements and ranked in the best roof anchors guide, with rated connectors where needed. Inspect the harness to the harness inspection checklist, and fit a suspension trauma strap for the rescue plan.

How the Workman Tie-Back compares

The MSA Workman Mini is the most compact 6 ft PFL for lower-level tie-off; this Workman adds the 7.5 ft tie-back build for anchoring to large members. Against a lanyard like the twin-leg rebar SafeWaze V-Line, the PFL locks faster and stops shorter — the trade-offs are in the shock-absorbing lanyard vs SRL guide. For longer reach, a full-size self-retracting lifeline covers more distance — browse the SRL collection and the best self-retracting lifelines guide. Build a rig from the best fall protection kits. Everything lives in the fall protection collection.

Safety note: a personal fall limiter is one part of a personal fall arrest system — it works only with a rated full body harness and a rated anchor or structure, under OSHA 1926.502 and the MSA instructions. When you tie back around a structure, follow the instructions for the correct wrap and clip point and confirm the member is strong enough; keep one leg connected while you move the other; run the fall-clearance calculation for your anchor position and the device's lock-up distance; and remove the unit from service after any fall or any sign of load-indicator deployment.

Ordering FAQ

Is the MSA Workman Tie-Back PFL available?
Availability varies — this MSA model may show no current offer. Check the linked Amazon listing for stock and delivery before ordering.

What does tie-back mean on this SRL?
The retractable legs can wrap around a structural member and clip back to the device, so you can anchor to a large column or beam directly — no separate anchor connector needed for those members.

What is a personal fall limiter?
A personal fall limiter (PFL) is a compact self-retracting device. It retracts a short line and locks quickly in a fall, stopping you in a shorter distance than a fixed lanyard and allowing lower-level tie-off.

What does the twin-leg design give me?
Two retractable legs let you keep one clipped while you move the other, so you stay connected as you travel across a structure — continuous 100% tie-off, a direct alternative to a twin-leg shock-absorbing lanyard.

What is the ARCA harness connection?
MSA’s ARCA connection lets you attach the unit by inserting your harness dorsal D-ring into a slot on the device, rather than clipping a separate connector — a fast, intuitive harness attachment.

How long is the line?
7.5 ft of line length. Match the reach and your anchor positions to keep fall clearance in mind for the tie-back configuration you use.

What is it made of?
A thermoplastic housing with stainless-steel hardware, in yellow. It weighs about 6.6 lb.

How is it different from the Workman Mini PFL?
The Mini is the most compact 6 ft PFL; this Workman is the twin-leg tie-back model with a 7.5 ft line and the ARCA connection, built for tying back to large structures.

Do I still need to calculate fall clearance?
Yes — even with a personal fall limiter, confirm the required fall clearance for your anchor position and the device’s lock-up distance before working, following the MSA instructions.

Is the Workman Tie-Back OSHA compliant?
As the connecting device in a fall arrest rig, it works within a compliant setup with a rated full body harness and anchor or structure under OSHA 1926.502. Confirm the ratings on the product label.

How do I inspect it before use?
Pull the legs out and let them retract to check the action, confirm they lock under a sharp pull, check the housing, hooks, and tie-back function, and read any load indicator. Remove it from service after any fall or sign of deployment.

How do I reorder for a crew?
