HI Mike and Arch
Thanks for the feedback, sounds like i do not need to support it. MIke, your point about the expoxy shrinking is one I had not considered. The sheaths are indeed epoxied, at least where they exit the fuse. I would take a bit of hacking and then repair, but I could cut it out and replace with perhaps a non shrinking adhesive - perhaps Silicone? - any ideas

Thanks
