P-00147-60 Temporary Horizontal Lifeline Cable Assembly
The Malta Dynamics P-00147-60 is the cable that turns two MD Post stanchions into a working horizontal lifeline. It connects between two MD Posts - for steel I-beams (P-00041-1) or concrete beams (P-00041-10) - to complete a two-worker temporary horizontal lifeline fall protection system. Sold as one each, for temporary use only.
The assembly is the only point of attachment for personal fall protection on the system. It uses a 3/8 inch 7x19 galvanized aircraft cable, an in-line energy absorber, and bolt-type shackles to limit forces transmitted to the structure in a fall. The full system meets OSHA 1926.502 and is tested to ANSI Z359.1.
Who Needs This Product
The P-00147-60 is the lifeline cable for crews running a Malta Dynamics MD Post horizontal lifeline - steel erectors, concrete crews, and industrial teams who need a temporary two-worker tie-off line at height. It is not a standalone product. It requires two MD Post stanchions and proper anchorage to form a system, and each worker on the line wears an ANSI full-body harness with a shock-absorbing lanyard or self-retracting lifeline. Personal fall protection attaches to this cable, never to the posts.
Features
In-line energy absorber
A powder-coated steel in-line energy absorber, tested at 10,000 lb, reduces the forces transmitted to the attaching structure in a fall.
3/8 inch aircraft cable
A 3/8 inch 7x19 galvanized aircraft cable, tested at 14,400 lb, spans up to 60 feet between two MD Posts.
The only tie-off point
This cable is the sole attachment point for personal fall protection on the system, so the load path stays engineered and predictable.
Bolt-type shackles and thimbles
7/16 inch galvanized bolt-type shackles tested at 15,000 lb and heavy-duty galvanized thimbles connect the assembly to the stanchions.
Turnbuckle tensioning
A turnbuckle pre-tensions the cable to the system's sag chart so the energy absorber works as designed.
Works on both posts
Spans between two P-00041-1 I-beam posts or two P-00041-10 bolt-on posts to complete a two-worker system.

The energy absorber is a single-use item. Inspect it regularly for elongation. The absorber is orange with a white band beyond the orange on the shaft - if it is elongated and black shows beyond the white band, pull it from service immediately and replace it. After any fall the system must not be used again until carefully inspected. Connect and disconnect only at the safety shackles, never exceed two workers, and confirm fall clearance before tying off.
Compliance Standards
OSHA 29 CFR 1926.502
Construction fall protection systems criteria, including horizontal lifeline and anchorage requirements.
ANSI Z359.1
Fall protection code the horizontal lifeline assembly is designed and tested to.
Two-Worker System Limit
The assembly is a two-person rated lifeline when installed to proper anchorage devices.
Single-Use Energy Absorber
The in-line energy absorber must be retired and replaced after any deployment or elongation.
Typical Applications
Installation Overview
Install per the Malta Dynamics MD Post horizontal lifeline system manual. The sequence below is an overview only.
- Inspect. Confirm the assembly shipped complete and undamaged, with the energy absorber not elongated.
- Set the posts. Install two MD Post stanchions to proper anchorage, spaced up to 60 feet apart.
- Extend the turnbuckle. Fully extend the turnbuckle before connecting the assembly.
- Connect. Attach the energy absorber end to the center post and the clamp and thimble end to each end post, securing every shackle with the nut and cotter pin.
- Tension. Pretension the cable at the turnbuckle to the sag chart - 5 to 6 inch sag on a 41 to 60 foot span - and torque all nuts to 45 ft-lb.
- Verify clearance. Confirm fall clearance below the work surface before any worker ties off.
Inspection and Retirement
Inspect before each use, and walk the installed line weekly checking for loose posts and absorber elongation. Remove the assembly from service for any of the conditions below.
- Energy absorber: orange shaft elongated with black showing beyond the white band - retire and replace.
- Cable: kinks, broken wires, birdcaging, or corrosion on the 3/8 inch aircraft cable.
- Hardware: damaged or corroded shackles, thimbles, turnbuckle, or machine-crimped clamps.
- Connections: any attempt to disassemble the assembly at a point other than the safety shackles.
- Labels: must remain legible and intact.
Retirement trigger: after any fall-arrest event the system must not be used again until carefully inspected, and the single-use energy absorber must be retired and replaced.
