DIY or just smarter than I fedi, I need help on two things. (UK based if makes a difference) 1) Need to replace the old night latch, its a cheap feeling case thing, I swapped the lock easily but hate the case. Unfortunately living in a block of flats I can't drill any more holes in my door. Am I correct in thinking the mounting plates for night latches are more or less standardised? If I buy a new latch I can use the old door mount/replace it without needing new holes 2) my flat has what I'm told are "lamp sockets". To me they look like BS 546 from a theatre but smaller (so sub 15A). As far as I am aware these are really old standards, but my building is about 2006, my question is: are these OK to use? Can my IKEA G plug lamps and such use this if I can find some adapter or some easy way to tell? Or am I stuck with annoying two switch light switches that only have one usable switch and useless sockets? #DIY #askfedi #fedihelp #electricity #lockstodon
