Kratos Roofer Fall Arrest Kit - Guided Fall Arrester and 10m Kernmantle Rope Line

Kratos Roofer Fall Arrest Kit

This kit is built for roofers working on pitched or flat roof structures where a fixed-length lanyard is not practical. The guided fall arrester runs directly on the 10m kernmantle rope anchorage line, travelling with the operative as they move and locking instantly in the event of a fall. Everything needed to deploy a compliant three-component fall arrest system arrives in a single jute carry bag, certified and ready to use.

Why choose the Roofer Fall Arrest Kit

• Guided fall arrester on rope: Unlike a fixed-length lanyard, the arrester moves freely up and down the rope with the operative, locking only when triggered by a fall. This allows continuous movement without disconnecting and reconnecting.

• 10m kernmantle rope anchorage line: Gives enough vertical range to cover most domestic and commercial roof pitches from a single anchor point, reducing the need to reposition the system mid-task.

• Integrated energy absorber: Built into the fall arrester unit, reducing peak arrest force transmitted to the harness wearer and limiting injury risk during a fall event.

• Steel screw-locking karabiner: The 18mm gate opening accommodates most standard anchor hardware, and the screw-lock gate eliminates accidental opening under load.

• Full body harness with two attachment points: Distributes arrest forces across the whole body. Two attachment points give flexibility for different anchor configurations on site.

• Certified as a matched system: All components carry CE marking and are certified compatible with one another, satisfying the EN365 requirement that all three elements of a fall protection system must be certified and compatible.

• Jute carry bag: Keeps the harness, arrester, and rope clean and protected between uses, extending service life and simplifying daily kit checks.

A fall protection system must include at least three components:

1: The gripping system of the body: harness, belt.

2: The fall arrest system: fall arrest on anchor line, retractable fall arrest, energy absorbing lanyard.

3: The anchoring system: anchor lanyard lifeline, tripod...

The user security can be guaranteed only if:

• These three components have the CE marking ;
• These three components are compatible together ;
• The user has been trained in the usage of these three components.

! A fall arrest system can be complete only if a rescue plan has been established in advance in order to cope with any emergency that may arise during work.

 Specifications

Compatibility

Who is this for?

This kit is for trained roofers, roofing contractors, and site operatives carrying out work on pitched or flat roofs where a fall arrest system is required by the method statement. It suits both domestic and commercial roofing projects and is appropriate for operatives who need to move vertically along a roof surface without repeatedly disconnecting from their anchor system.

Typical applications

• Pitched roof work on domestic or commercial buildings where guardrails are not practicable
• Flat roof maintenance and repair where edge protection is absent or incomplete
• Roof light installation and repair on industrial or warehouse structures
• Velux and skylight work on residential properties
• Solar panel installation on pitched roofs
• Roofing inspection tasks where a full scaffolding solution is disproportionate to the risk
• Any roofing task where a RAMS document specifies a guided type fall arrest system

How to use

1. Inspect all components before use. Check rope for cuts, kinks, or contamination. Check the arrester mechanism for damage and confirm it slides freely on the rope. Check the karabiner gate closes and locks correctly. Do not use any component that fails inspection.
2. Install the rope anchorage line from a rated, fixed anchor point at the highest practicable position above the work area. The anchor must be assessed and rated for fall arrest loading by a competent person.
3. Thread the kernmantle rope through the guided fall arrester. Confirm the arrester is orientated correctly per the manufacturer's markings before loading.
4. Connect the steel screw-lock karabiner to the guided fall arrester and then to the front or rear attachment point on the harness. Tighten the screw gate fully.
5. Don the harness and adjust all straps: chest first, then thighs, then shoulders. The harness should be snug with no more than two finger widths of slack at any strap.
6. Move the arrester up the rope by hand before beginning work. It should travel freely upward and lock when pulled sharply downward. Confirm this before applying body weight.
7. Work within the range of the rope. Do not allow excess slack to accumulate below the arrester, as this increases free-fall distance.
8. On completion, remove the karabiner from the harness first. Remove the arrester from the rope. Recover the rope and anchor. Stow all components in the jute bag.

Safety and maintenance

Safety during use:

• This is a fall arrest system, not fall restraint. It arrests a fall after it occurs. Where practicable, collective protection such as edge guardrails should be the primary control measure.
• The anchor point must be positioned as high above the work area as possible. A low anchor increases free-fall distance and arrest forces on the body.
• Wear a hard hat to EN397, safety footwear to EN ISO 20345, and appropriate gloves. Roof surfaces present slip and edge hazards beyond the fall arrest risk.
• Never use a deployed or damaged energy absorber. If the arrester shows signs of activation, withdraw it from service immediately.
• Suspension trauma can develop rapidly in an arrested worker. A rescue plan must exist before work begins, as required under EN365.

After use and maintenance:

• Wipe down the rope, arrester, and karabiner after each use. Remove dirt, moisture, and any chemical contamination before storage.
• Dry all components naturally away from direct heat before returning to the jute bag.
• Inspect the kernmantle rope along its full length at each use. Any cut, abrasion, stiffness, or discolouration is grounds for withdrawal.
• All components must be formally inspected by a competent person at least every 12 months, with records kept per PUWER requirements.
• Withdraw the entire kit from service immediately after any fall arrest event. The energy absorber is single-use and cannot be reset.

Frequently Asked Questions

Q: What is the difference between this kit and the Scaffolder Fall Arrest Kit?

 A: The key difference is the connection system. This kit uses a guided fall arrester running on a 10m rope anchorage line, which allows the operative to move vertically across a roof surface while remaining continuously connected. The Scaffolder Fall Arrest Kit uses a fixed 1.8m energy absorbing lanyard with scaffold hooks, designed for connection to scaffold tubes at a fixed working position. Roofers need range of movement along the rope; scaffolders need a short, direct connection to a scaffold structure.

Q: What do EN361, EN354, and EN355 mean and why do they matter?

 A: EN361:2002 covers full body harnesses, setting requirements for how arrest forces must be distributed across the body. EN354:2002 covers lanyards and connection components. EN355:2002 covers energy absorbers, specifying the maximum force that can be transmitted to the wearer during an arrest. All three standards are required under the Personal Protective Equipment at Work Regulations 1992 and Working at Height Regulations 2005 for fall arrest PPE used on UK sites. CE marking to these standards is the legal declaration of compliance.

Q: Does this kit include an anchor point?

 A: No. The kit provides the harness, guided arrester, rope, and karabiner. A rated, fixed anchor point must be separately installed at the top of the rope by a competent person before the system is used. Common anchor options for roofing include roof anchor plates, ridge anchors, and structural eyebolts, each of which must be assessed for the loads generated by a fall arrest event.

Q: Can the guided fall arrester be used on any rope?

A: No. The arrester is designed and certified for use with the kernmantle rope supplied in this kit. Using the arrester on a different rope diameter, construction, or material may prevent it from locking correctly in a fall. Always use the arrester with the rope it was supplied and certified with.

Q: What is the maximum rope length I can use with this system?

 A: The kit is supplied with a 10m rope. Do not extend or substitute the rope. The certified performance of the guided arrester is based on the rope specification supplied. If greater vertical range is required, a different system should be specified by a competent person.

Q: What happens if the kit is used in a fall arrest event?

 A: Withdraw the entire kit from service immediately. The energy absorber is single-use and cannot be inspected, reset, or reused after deployment. The rope and harness may also have sustained damage not visible to the naked eye. Label all components as withdrawn, quarantine them, and have a competent person assess before any decision on disposal or return to service. The operative should also be assessed by a first aider: suspension trauma symptoms can be delayed.

Q: How often must this kit be formally inspected?

A: Pre-use inspection by the wearer is required before every session. Formal inspection by a competent person is required at intervals not exceeding 12 months, with written records kept. Most manufacturers also specify a maximum service life of between five and ten years from date of first use. Check the manufacturer's label for the specific figure applicable to this kit.
