CONSTRICTOR - THE STANDARD BASE TEXTILE BLOCKER

Three times lighter and offering twice the holding power of conventional metal rope clutches, the Constrictor textile rope clutch is revolutionising sailing, from racing to cruising. Remarkably simple and highly effective, this locking system works on the principle of a textile sleeve. A braided sleeve made from Technora aramid fibres tightens around the rope under tension, locking it instantly. The greater the tension, the stronger the grip. Unlike conventional metal rope clutches, the rope is not crushed between two cams, preventing deformation, stripping and abrasion. To release the rope, simply retract the sleeve. Release remains easy even under heavy loads.

Key benefits:

Proven performance with twice the holding power. Extremely lightweight, weighing three times less than a conventional rope clutch. A rope-friendly system that can double rope service life.
Easy release, even under load, including remote operation using the pull cord.

Applications:

Used by top sailors:
Maxi yachts, Mini class boats, multihulls and IMOCA yachts are among the many vessels equipped with our Constrictor textile solution. Drawing on our experience with high-performance sailing boats, we now offer a more ergonomic model. It is ideal for cruising sailors looking for simple, effective solutions. CONSTRICTOR can be installed at the masthead (sail hook) or beneath a coachroof fairing (sheets and halyards). Its compact design makes it particularly discreet.

Construction:

CONSTRICTOR consists of:
– A metal mounting base supporting the sleeve.
– A specially braided sleeve made from high-strength black Technora fibres.
– A Dyneema pull cord for releasing the clutch.

Details:

Technora Black aramid gripping sleeve:
Specially designed braided structure.
High-strength black fibres.
Good UV resistance.

Metal mounting base:
Made from anodised aluminium, the base features two mounting holes for 6 mm or 8 mm screws, depending on the model (with the same hole spacing as conventional rope clutches).

Locking and release system:
Simple and effective, an opening in the base allows the pull cord to slide, locking or releasing the Constrictor.

Braided Dyneema pull cord:
Allows remote release of the rope clutch, even under load.

Elastic sleeve-retaining cord:
Keeps the sleeve in position when the textile rope clutch is released.

Product range:

CONSTRICTOR is available in five sizes, from No. 6 to No. 14. Each number corresponds to the recommended rope diameter (for example, No. 8 for an 8 mm rope).

CONSTRICTOR is compatible with most existing ropes, except those with Dyneema or Spectra fibre covers or additional protective sleeves.
