Yes. The MSA VTOHW-012-RA-A is a twin-leg (two-legged) V-TEC Personal Fall Limiter designed for 100% tie-off — because it has two independent self-retracting legs, the worker keeps one leg anchored while relocating the other, so they are never disconnected while moving at height or climbing. Each leg has a 6 ft (1.8 m) retractable HMPE web lifeline ending in a large AL36CL aluminum snaphook that clips to the overhead anchorage points, while the unit mounts to the harness dorsal D-ring through a TLALTAK twin-link aluminum triple-action carabiner. It meets ANSI Z359.14-2021 (Class 1) and OSHA 29 CFR 1910.140 & 1926.502, making it well suited for construction, general industry, and oil & gas.

The MSA VTOHW-012-RA-A V-TEC Personal Fall Limiter is tested to ANSI/ASSP Z359.14-2021 and complies with OSHA 29 CFR 1910.140 and 1926.502. It is classified as an ANSI SRL Class 1 (Non-Leading Edge) device, meaning it is rated for overhead anchorage where the anchor is at or above the dorsal D-ring, not for foot-level or leading-edge tie-off. Its gray housing follows MSA's color code (gray = overhead use only; green = leading edge).

A Personal Fall Limiter (PFL) is a compact self-retracting lanyard (SRL) that mounts on the worker (typically at the harness dorsal D-ring) and pays out and retracts a short lifeline as they move, locking instantly to arrest a fall over a very short distance. The MSA VTOHW-012-RA-A is a twin-leg version: two 6 ft (1.8 m) retracting HMPE web legs let the worker "leapfrog" anchor points — one leg always stays connected while the other is moved — for continuous 100% tie-off. Each leg locks on sudden loading to stop a fall quickly, and a built-in visual load indicator shows whether the unit has already arrested a fall.

No. The MSA VTOHW-012-RA-A is an ANSI Class 1, Non-Leading Edge device with a gray housing, which in MSA's color code means overhead use only — the anchorage must be at or above the user's dorsal D-ring. It is not rated for leading-edge (sharp-edge, foot-level) applications. For leading-edge work, MSA offers a green-housed V-TEC Leading Edge model instead. Always confirm the anchorage is overhead before using this gray unit.

The MSA VTOHW-012-RA-A V-TEC PFL is rated for 310 lb per ANSI and up to 400 lb (181 kg) per OSHA, including the worker plus tools and equipment. It is a single-user device. As MSA notes, always check the product label for the allowable capacity for your configuration before use.

On the MSA VTOHW-012-RA-A, the AL36CL is a large aluminum snaphook at each lifeline (leg) end — it connects to the overhead anchorage points. The TLALTAK is a Twin-Link aluminum triple-action carabiner at the housing (top) end that joins both PFL legs into a single connector and attaches the unit to the worker's harness dorsal D-ring. Both are aluminum, keeping the assembly lightweight, and the triple-action gate requires three deliberate motions to open, preventing accidental roll-out.

The MSA VTOHW-012-RA-A uses a durable polycarbonate clear housing so the SRL's critical internal components are visible for quick pre-use inspection — you can see the retraction mechanism without opening the unit. It also carries an RFID tag for electronic inspection tracking and a visual load indicator that shows whether the device has already been subjected to a fall (and should be removed from service). Together these features simplify the required periodic and pre-use inspections.

The MSA VTOHW-012-RA-A is a twin-leg V-TEC WEB Personal Fall Limiter with two 6 ft (1.8 m) HMPE web lifelines (each 1.00" wide × 0.14"/3.8 mm thick), a polycarbonate clear housing, and aluminum hardware — an AL36CL large snaphook and a TLALTAK twin-link triple-action carabiner. It weighs 6.08 lb (2.76 kg), is gray (overhead use only), operates from -40 °F to 130 °F (-40 °C to 54 °C), and includes RFID and a visual load indicator with a 360°/180° rotating attachment point. It meets ANSI Z359.14-2021 (Class 1) and OSHA 1910.140 & 1926.502.

For most overhead work, yes. A traditional shock-absorbing lanyard can allow several feet of free fall before it deploys, needing large fall clearance, and a single lanyard forces you to disconnect to relocate. The twin-leg MSA VTOHW-012-RA-A is a self-retracting PFL that keeps the lifeline taut and locks almost immediately, greatly reducing free-fall distance and required clearance, while its two legs give continuous 100% tie-off. It is also compact and lightweight (6.08 lb) with all-aluminum hardware. The trade-off: as an ANSI Class 1 device it is for overhead anchorage only, not leading-edge use.

The MSA VTOHW-012-RA-A V-TEC PFL Twin-Leg (6 ft, with large aluminum snaphook and TLALTAK triple-action carabiner) is available at Industrial Safety Products (industrialsafetyproducts.com) with free shipping. It's a twin-leg, 100% tie-off self-retracting lanyard certified to ANSI Z359.14-2021 (Class 1, overhead use) and OSHA 1910.140 & 1926.502, suited for construction, general industry, and oil & gas work at height.
