Product / Vertical Fall Protection

Cabloc and Railok fall protection systems provide a safe means of access on vertical structures such as fixed ladders, masts, gantries and silos for maintenance purposes.


Cabloc is a vertical tensioned cable system which is clamped to the top of a structure such as a fixed ladder to provide fall protection for those accessing the ladder. The system is extremely flexible in its application and provides the operative with completely hands free protection.   The system has been designed for areas where wind loading prevents the use of a track based system such as Railok, or for instances where a track system would hinder the general use of the system.

Cabloc provides hands free protection

Cabloc features a tensioned galvanised or stainless steel cable with solid core strands to prevent deformation under load.  The cable is clamped to the top of the ladder with an impact indicating shock absorber and then at intermediate points along the length of the stringer.  These intermediate brackets enable the cable to be released when the arrester device passes through.  The tensioned cable then simply springs back into the bracket once the devise has passed through.  An arrester device with a double cam brake is connected to the cable and via a karabiner to the operative's harness.

  • Tensioned galvanised/stainless steel cable prevents deformation under load
  • Provides hands free protection
  • Built in tension indicator guarantees correct installation



Railok is designed to prevent falls from fixed ladders or similar structures and comprises a rail which is permanently attached to the ladder or structure and a trolley which runs on the rail.    The system is fixed with universal mounting brackets which enable connection to a wide range of rung and stringer profiles and sizes.

Railok trolley with energy dissipating unit 

When the trolley is in the free-running, unlocked position, the outer ends of the arms are inclined upwards at an angle of around 10°; the horizontal brake pads come into contact with the front face of the rail and lock the trolley.  In the event of a fall, an Energy Dissipating Unit (EDU) ensures that the maximum force on the body does not exceed 6kN.

  • Designed for use on fixed ladders or similar structures
  • Allows users to ascend and descend uninhibited
  • Energy Dissipating Unit reduced the force on the body in the event of a fall
  • Unique fail safe design


NOTE:  All fall arrest & PPE equipment must be regularly inspected and re-certified in accordance with BS EN 365 Personal Protective Equipment against falls from height – General requirements for instruction for use and marking.
