I've seen a cheap standard mechanical metal part used for that. It's a domed top with spring fingers dangling below it (think 'jellyfish'). It was modified by the user by having a bite taken out of the edge, using a simple press tool, allowing the fibre to pass through. Far cheaper than a conducting grommet and worked well. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
