Since 1978, Barry Cordage Ltd. has been manufacturing and distributing a wide range of industrial-grade, rope-related products and services. Barry's fabrication standards meet or exceed strict industry norms and reflect their unique expertise and innovated solutions with textile applications.

D.E.W. Longlines (Dielectric Even Wet) are an advanced helicopter longline product designed specifically for external load missions where negligible electrical conductivity is required. The ultra high-strength loadbearing synthetic rope is completely encapsulated in a proprietary thermoplastic extrusion resulting in a longline that is dielectric even in humid conditions.
