[QUOTE="poni, post: 522251, member: 1497"] i always wondered why we have to use a banjo on SWA into metal boxes ,in plastic i can see why, but in metal boxes,if the back nut and gland are tight when the earth path is good and you should not need the banjo, but if the back nut and gland are lose, the banjo will be lose, so no point having it there in the first place, then there are ones that do the gland and banjo into plastic boxes, how tight can you get on a plastic box ,(does the plastic not just move out of the way ) i use two back nuts ( one for the banjo and the other for the going onto the box), but i do like the piranha nuts a good earth every time no matter how tight the gland is, [/QUOTE]
