The connecting construction (snap-together) that is free from sliding part minimizes the generation of dust
Link-against-link friction noise, which is generated when links are traveling, is significantly reduced, thanks to use of soft material of low percussive noise.
Since the main inner part in contact with cables is made up with soft material, though rigidity is maintained by a framework structure, the abrasive wear on cables decreases remarkably.
Clean level of class 1000 is achieved.
Flaps are made of same material as Plarailchain SP series, making it possible to further increase rigidity while decreasing cable abrasion.
The flap opens at both sides. It is also removable.
The structure of a hard material frame combined with a soft material frame prevents rigidity reduction, which is incidental to soft material based products.
