VertiGuard™ 400 · Vertical lifeline for fixed laddersClimb connected, top to bottom.
VertiGuard 400 is a permanent vertical lifeline for fixed ladders. A stainless rope grab rides an 8 mm wire rope with the climber and locks instantly in a fall. An extension arm keeps them connected as they step off at the top.
For ladders people climb every day
Fixed ladders on towers, tanks, silos, stacks and building façades.
Telecom and transmission towers
Long ladder climbs where a rest-and-reclip system slows crews down.
Tanks, silos and stacks
Process-plant ladders exposed to weather and corrosive air.
Building access
Roof-access ladders and cat ladders on façades and plant rooms.
Wind and energy
Repetitive climbs where a guided arrester is safer and faster.
Rope, guides and a rope grab that follows you
The line is anchored at the top and bottom of the ladder, held in line by intermediate guides every 10 m, and tensioned so the rope grab runs smoothly and locks reliably.

Why a guided vertical line
- Both hands on the ladder. The rope grab travels with the climber; nothing to move or re-clip.
- Locks instantly in a fall, on the rope, close to the climber.
- Stays connected at the top. The extension arm carries the line 1.5 m above the platform for a safe step-off.
- Fits most ladders. Brackets cover rungs from Ø18 mm to Ø70 mm, and the top bracket fits side rails too.
- Built for weather. Stainless steel with electropolished or CED finishes.
Rope grab compatibility. VG400-09 is for Ø8 mm 7×19 steel wire rope only. Do not use it on other ropes.
Every part, and what it does
Nine components cover the anchorage, energy absorption, tensioning, guidance and the climber's connection.
Top mounting bracket
Universal top (or bottom) anchorage that fits rungs or side rails with two studs.
Shock absorber
Attenuates the arrest load so less of it reaches the ladder. U-bolt connection to the rope.
Tensioner
Joins the rope to the shock absorber and pre-loads the line so the rope grab runs true.
Crimping assembly
Forms and protects the rope eye: thimble, aluminium ferrules and rope cap.
U-bolts and thimble
Mechanical loop formation and eye protection at rope terminations.
Intermediate bracket
Cable guide that stops sway and keeps the rope on the right path for the rope grab.
Bottom mounting bracket
Double-rung extremity plate for the bottom of the line, spreading load across two rungs.
Extension arm
Carries the line 1.5 m above the top of the ladder so the climber stays connected while stepping off.
Rope grab
Guided-type fall arrester that follows the climber and locks instantly in a fall.

Specified to recognised standards
EN 353-1:2014+A1:2017
Guided-type fall arresters on a rigid anchor line, the standard for vertical ladder lifelines.
The anchorage brackets, shock absorber, intermediate bracket and rope grab are listed to EN 353-1:2014+A1:2017. The tensioner, crimping assembly, U-bolts and extension arm are listed against their static-strength test requirements.
Make your VertiGuard™ 400 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
