Guys, I just finished installing a shower using 10mm cable. There were 2 jobs I hated: (1) somehow getting the 10mm conductors into the back box so I could fit the pull-switch, and (2) Nailing the metal capping over the cable using 'masonry' nails. 75% of the nails bent and I hit my fingers several times trying to hold the nail in place on the bouncy metal. Any tips from you Pro's out there would be greatly apriciated for next time. Cheers, Alex.
