Three times lighter, twice the breaking load of conventional metal clutches, constrictor® opens a new era for sailing deck hardware for racing and also cruising.

Extremely simple and totally efficient, this system uses the principle of squeezing capacity offered by braided sleeves.

As the line comes under load it is instantly squeezed by the Aramid Technora® sock. The more the tension, the more it holds. The rope is not pressed between two metallic parts as with conventional clutches: It is not distorted, subject to wear or chafe.

It is released by simply retracting the sleeve, which is easy even under heavy load.


Proven efficiency, by a factor of two compared to conventional clutches.
Very light: three times lighter than conventional clutches.
Gentle with the rope (ropes last twice as long).
Easy release with the drawstring even under heavy load.


Black Technora® holding sock:
Specifically braided sock.
High tenacity black fibre.
Good resistance to UV.

Metal holding base:
Made of anodised aluminium, this base features two mounting holes for 6mm or 8 mm screws depending on the model (the same as the standard clutches distance between the holes).

Locking / release system:
Easy and efficient, the aperture in the base provides a clear route for the line to run through allowing easy control of the Constrictor® release and locking functions.

Braided Dyneema® drawstring:
Allows remote release of the clutch under load.

Draw shock cord:
This elastic cord applies a constant tension to the jacket when the clutch is released.


CONSTRICTOR® is compatible with most of the existing ropes (except Dyneema®, Spectra® and similar covers).
