3M DBI-SALA 1244311 ShockWave 2 Single Leg Shock Absorbing Lanyard — 6 ft, Snap Hook + Rebar Hook

The 3M DBI-SALA ShockWave 2 single leg shock absorbing lanyard explained

The 3M DBI-SALA 1244311 ShockWave 2 is a 6 ft single leg shock absorbing lanyard with an elastic web. The tubular polyester webbing stretches as you reach out and draws back short when slack, so there is less line to drag, snag, or trip over, and an energy-absorbing design limits the fall-arrest forces on your body if you fall.

As an elastic shock absorbing lanyard — essentially a premium stretch lanyard — this 6 ft single leg lanyard pairs a self-locking snap hook at one end with an aluminum rebar hook at the other. Buyers looking for the single-leg shockwave 2 lanyard are usually after exactly that: a light, stretchy lanyard that reaches structural steel.

Pros & cons

Specifications

What this lanyard is for

Single-anchor work on rebar and structural steel — steel erection, bridge, tower, and general construction where you tie off to one point and want a stretchy lanyard that stays out of the way. It is ranked in our fall protection lanyards guide, and it is the connecting-device stage of the ABC system explained in our fall protection equipment guide and the ABCDs of fall protection. Because it is a lanyard and not a reeled SRL, plan for full lanyard fall clearance below your feet.

Compatibility

The snap hook clips to the dorsal D-ring of a full body harness, ranked in our safety harness guide. Inspect the harness and the whole rig per our harness inspection reference before every use.

How the 1244311 compares

The 1244311 is the single-leg ShockWave 2; its twin, the 1244409 twin-leg 100% tie-off, adds a second leg for continuous tie-off. Against 3M's other single-leg 1241460 shock absorbing lanyard, the ShockWave 2 swaps in a rebar hook and stretch web. Compare adjustable single legs like the MSA Workman single-leg, the SafeWaze FS560-AJ, or the positioning-friendly Guardian 01285. If you actually need a reeled device that locks in inches, compare our self-retracting lifelines and read the trade-offs in shock-absorbing lanyard vs SRL.

Safety note: a shock-absorbing lanyard is one component of a personal fall arrest system — it works only with a rated full body harness and a rated anchor under OSHA 1926.502. A single-leg lanyard needs full fall clearance below your feet (free fall plus absorber deployment plus your height plus a safety margin) and leaves you unprotected for the moment you unclip to move, so verify your clearance, plan your moves, inspect the web and both hooks before every use, and retire the lanyard after any fall.

Ordering FAQ

Is the 3M DBI-SALA 1244311 ShockWave 2 in stock and ready to ship?
Availability changes — open the linked listing for live price, stock, and delivery speed before you order.

Is the 1244311 single-leg or twin-leg?
Single-leg. It protects you at one anchor at a time. If you need continuous 100% tie-off while moving between anchors, use the twin-leg ShockWave 2 (1244409) instead.

How long is it?
6 ft. The elastic web stretches in reaction to your movement and draws back short when slack, so there is less line to drag, snag, or trip over.

What connectors does it have?
A self-locking snap hook at one end that clips to your harness back D-ring, and an aluminum rebar hook at the other end for clipping to rebar or structural steel.

What does the stretch web do?
The tubular polyester web is elastic, so it extends as you reach out and contracts when you move back in. That keeps the lanyard out of your way and reduces trip and snag hazards versus a fixed-length web lanyard.

How does it protect me in a fall?
It has an energy-absorbing design that limits the fall-arrest forces transmitted to your body during a fall. Always inspect the lanyard before use and retire it after any fall.

Is this a self-retracting lifeline (SRL)?
No. It is a shock-absorbing lanyard with an elastic web, not a reeled SRL. It needs full lanyard fall clearance below you, not the few inches an SRL needs. If you need a reeled device, see our self-retracting lifelines guide.

What is the rated weight capacity?
The manufacturer listing does not print a single capacity figure. Confirm the rated capacity range in the 3M user guide and on the product label, and keep total weight (worker plus tools) within the lowest rating in your connected system.

Is it OSHA and ANSI compliant?
3M labels it for industrial/occupational use and states its products must be used in compliance with OSHA and ANSI. The listing does not print a specific ANSI Z359 sub-number, so confirm the current standard and edition in the 3M user guide for your application.

Where does it connect on my harness?
The snap hook clips to the dorsal (back) D-ring of a full body harness; the rebar hook clips to a rated anchor or structural member.

How do I inspect it before use?
Run the full length of web through your hands for cuts, fraying, burns, or chemical damage; confirm the energy-absorbing element is intact and not deployed; check the snap hook and rebar hook for cracks, corrosion, and correct self-locking gate action. Remove from service after any fall or sign of deployment.

How do I reorder for a crew?
Reorder from this page — the listing and its linked item stay constant, so matching a crew's single-leg lanyards from the lanyards & lifelines collection takes seconds.
