SafeXtra™ 500 · Overhead horizontal lifelineAnchorage above, freedom below.
SafeXtra 500 is a permanent overhead lifeline, bolted to steelwork, concrete or engineered anchor points above the work area. Workers connect a self-retracting fall arrester to the trolley and move freely along the line beneath it.
For work below a beam or roof structure
Where the hazard is beside or below the worker and there is structure above them.
Loading bays and tankers
Access to vehicle tops, tankers and rail wagons from the ground or a gantry.
Hangars and workshops
Work on aircraft, vehicles and machinery under a roof structure.
Platforms and mezzanines
Open edges where guardrails get in the way of the job.
Crane runways and gantries
Maintenance along a long steel structure.
Anchored overhead, connected through an SRL
End plates bolt to the structure at each end. The shock absorber and tensioner sit at one end of the 8 mm rope; the worker's self-retracting fall arrester hangs from the trolley and follows them along the line.

Every part, and what it does
The SX500-01 end plate is unique to SafeXtra 500; the rope and line components are shared with MaxSpan 300.
End extremity plate
Bolted end anchorage for overhead lines on steelwork, concrete and engineered anchor points.
Shock absorber
Spring-type energy absorber that cuts the load reaching the anchors and roof in a fall.
Tensioner
Swageless tensioner: sets the line length and tension, and joins the cable to the shock absorber.
8 mm SS316 wire rope
The lifeline itself: flexible 7×19 stainless rope for smooth trolley travel.
Detachable trolley
The user's connection point. Rolls the full length of the line, through intermediate brackets, without unclipping.
Cable extremity
Swageless termination at the far end of the 8 mm rope. No swaging tools on site.
Intermediate bracket
Holds the 8 mm rope along the run, splitting it into shorter spans to cut sag. The trolley passes straight through.

Anchor devices. Type A for structural anchors such as the roof posts and OH end plate; Type C for horizontal flexible anchor lines.
CEN/TS 16415:2013
Anchor devices for use by more than one person at a time. Listed for the shock absorber, tensioner, cable extremity and OH end plate.

Make your SafeXtra™ 500 tell you when it is used.
A fixed line is passive: nobody knows it arrested a fall until someone looks. LineAlert fits inline beside the shock absorber, measures line tension around the clock, and sends a fall alert to your team's phones within a minute, over LTE, powered by its own solar panel.
- Fall alert in ≤ 1 minute, via the LineAlert app
- Slack or wear alerts before the line goes out of tune
- Retrofits to existing lines: no new posts, no cutting, no shutdown
- Every site on the JarshConnect dashboard and the Jarsh LineAlert app

Layout and bill of materials
We recommend the system, anchor positions, spans and every component, so you know exactly what is going in.
Supply and installation support
Components ship with their instructions. Talk to us about installation for your site.
Inspect and monitor
Inspect to each component's instructions, and add LineAlert so the line reports falls and slack on its own.
