    Steel karabiner with screw lock.

    Key Features

    • Opening 18 mm. 20kN.

    Industry / Job : Construction & Civil, Rescue & Emergency, Travel & Tourism

    Hazard / Risk : Fall

    How To Use

    Instruction for use:

    • This harness is recommended for all types of height interventions (frames, roofs, glass roofs, scaffoldings, traveling cranes,), for simple works, of a short period or occasional.
    • A harness must be strapped to the body as tight as possible but not excessively to allow total freedom of movements to the user.

    Instructions for storage:

    • The harness must be hung up by the rear D-ring in a temperate, dry and ventilated room away from sun rays and rodents and humidity or placed loosely in a container.
    • Keep the harness in its original packaging when not in use, or when transporting.
    • Transport the component or system in a package to protect it from any cuts, moisture or ultraviolet light.
    • Avoid corrosive, overheated or refrigerated atmospheres (freezing temperatures).

    Tests Conducted

    • Static (tensile) strength: the static (tensile) strength requirements are for the karabiner to withstand typical loads of 20kN in the main direction of force for three minutes. If this weight seems high when compared to a person with a weight around 1kN (roughly 16 stone), it should be noted that the dynamic forces as a fall is arrested can be much higher than the dead weight of the load alone. In addition, the requirement includes a factor of safety of more than 2.5 (assuming a maximum arrest force of 6 kN is allowable in a system).
    • Corrosion test: Corrosion can affect karabiners as they are often used in external and potentially harsh environments. Corrosion can weaken the karabiner, affecting the moving parts, so this needs to be tested. This is done by placing the karabiner in a corrosive atmosphere of warm saltwater mist for 48 hours (EN 362). A visual assessment is carried out to determine if corrosion has taken place. At SATRA we can also assess the static strength of the karabiner after this procedure, to better judge if the karabiner has been affected by the corrosive atmosphere.


    • Compatible with all type of PPE.
    • This device is designed to be integrated with personal protective fall arrest systems, such as harnesses and lanyards.
