RANGE INFORMATION

 

THE NEW GENERATION IN ROPE CLUTCHES

Unlike all conventional clutches the Constrictor® system does not crush the rope between two metal surfaces. Instead, the loaded rope is held securely in a textile sock, itself attached to an anchor base. The rope runs freely through the sock in one direction, but is gripped instantly within the sock when running out in the opposite direction. This constrictor effect, patented by COUSIN Trestec, provides increasing holding power as the load increases.
 

 Stronger :

The standard Constrictor® range provides 2x the holding power of conventional rope clutches, and custom solutions are available with holding power up to the break load of the rope!
 

 Lighter :

At least 3x lighter than conventional rope clutches.
 

No Abrasion or Rupture :

The unique textile sock closes like an octopus on the line, providing effective load distribution and outstanding grip; a result of fibre-to-fibre contact that is far less aggressive than traditional metal cams.
 

 Safely Release Under Load :

The line can quickly and easily be released under load without the need of a winch, simply by pulling the control lanyard. This can be an important safety consideration in situations where immediate release is required.

 
Remote Release System :

The Constrictor® control lanyard can be extended to provide remote release, making it ideal for applications such as mast-head mounted halyard to eliminate mast compression loads and halyard creep.
