The mounting thread of this lampholder has an internal locking screw to ensure secure fitting to the mounting thread. Another benefit of this lampholder from a user perspective is that the porcelain insert has terminals for live, neutral and earth allowing ease of wiring. Anyone who has tried to wire up a lampholder where the earth terminal is in the body of the cap will understand this is quite a relevant point! Solid machined lampholder just looks the part. You do need to keep an eye on the locking tabs and adjust (with a small screwdriver) when screwing the lampholder together. Fitted and assembled correctly this lampholder will outlast almost any other on the market. Fits a 40mm shade hole
