E4.1L - high dynamics, light and cost effective


All-rounder e-chains® and e-tubes for high dynamics. The E4.1L series was developed to combine the advantages of the E2/000 and E4.1 series in one series. On the one hand the stability of the E4.1 system and on the other the easy accessibility and assembly of the E2/000 system. The E4.1L system is the ideal energy chain for mechanical engineering and applications where there must be an optimum relationship between technical requirements and economic efficiency.
E4.1L New, very cable-friendly interior separation product range available.
E4.1L Pivoting and locking mounting brackets are available.
E4.1L KMA mounting brackets with all-round fixing option.
