Central Cord

The central cord act as the principal visual element. Along with its high mechanical resistance and its special coiling feature, the central cord will tenfold in length once it has been caught by the teeth of the bucket.

Stainless Steel Tracer Wire

The Plyage Hzd as an integrated tracer wire made of stainless steel AISI 304L of 0.8 mm covered in black polypropylene with a final diameter of 1.3 mm. It is detectable with on surface locating equipment for the underground networks.


The mesh is the support base of all active elements providing excellent flatness and easy installation.


Exterior Tapes

The exterior tapes are the secondary visual elements. Due to its longitudinal molecular orientation, the exterior tapes are highly resistant to rupture. The traction of the bucket will tear the tapes creating excellent in-trench visibility.
