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

"Allrounder" e-chains® and e-tubes for high dynamics. The E4.1L series has been developed to combine the advantages of the E2/000 and E4.1 in one series. The strength and stability of the E4.1 system combined with the easy accessibility of the E2/000 system. The E4.1L system is the ideal energy chain for mechanical engineering and applications of all kinds where there must be an optimum relationship between technical requirements and economic efficiency.

New, particularly cable-friendly interior separation program available.

 

Pivoting and rigid KMA mounting brackets available.

 

KMA mounting brackets with circumferential fastening options.

 
e-chain® selection aids

You can find the right e-chain® quickly by entering concrete parameters and with the aid of a comparison table.

Assembly instruction

Joining, separating and opening of the e-chain® and e-tubes.
