Features

The plachain duct, made of lightweight, highly durable engineering plastic, quietly and smoothly follows the motions of the movable areas of high-performance industrial robots, machine tools, transfer equipment, etc. It combines and arranges tubes and cables, with protection and guidance functions that prevent twisting and bending, to greatly improve equipment’s safety and maintenance.

PU series
The fully open type facilitates easy confirmation of internal situation. In addition, because the flap can be opened to either the left or right, replacement operating efficiency for tubes and cables is also greatly improved.

PO series
Protecting tubes and cables from dust, etc. this smart-looking fully covered type uses the same flap as the PU series, enabling it to be opened from either left or right.
