PLE energy chains are distinguished from standard plastic chains by their extreme stability and the rigid, continuously adjustable aluminum profile. Stay lengths up to 1000 mm can be accommodated. The allocation of the interior offers variable opportunities and guarantees optimum line protection even at high acceleration and travel speed. For space constraints, the PLP (PLE with plastic dividers) may be chosen. This inexpensive design allows secure guiding of large amounts of cable. The highly variable stay distribution opportunities through the small steps (3 mm) in height and the infinitely adjustable plastic telescopic dividers (PT) allow maximum space for all needs, even when changes in cable diameters are required.
