The Blocfor range ensures an automatic braking function in the event of a fall; the fall height is restricted by the immediate brake reaction.

The cable length is adjusted automatically thanks to a recall system integrated into the device, which offers the user a great deal of freedom of movement.

The Blocfor can also operate horizontally when used with a Tractel webbing lanyard - code 035032 – placed between the cable and the harness.

  • Complies with EN360.
  • Bottom Fitting: M46 - Snap Hook with fall indicator.
  • Breaking Strength: 15kN.
  • Braking Distance: 1m.
