PL615 Enclosure - Cable Gland Entry Positions. Cable Systems supply Cable Glands and other electrical products including Hawke EExe certified junction boxes to suit the customers requirements whilst still retaining certification. This is endorsed and backed by Hawke Cable Glands Limited, which offers customers a fast lane service for this product. This service is also available on industrial enclosures. In doing this, we have had to obtain certification by the Electrical Equipment Certification Service (EECS) for the Stockist Assembler Scheme. This was attained in 1994 and allows ourselves to issue our own Licence with the BASEEFA certificate.
