[E27 Lampholder]
Continental Style Pendant Lampholder ES / E27 Cordgrip Entry, Shade Compatible (Lock Ring Not Included)
Total Height: 75mm, Width: 40mm, Height excl Cordgrip: 55mm
Cheap, cheerful no frills continental style lampholder, just does what it says on the tin. Not really designed to be seen, a utility ES (E27) lampholder designed to hang off a wire, especially useful if you have a light shade that has a 40mm fixing hole, used with 2 shade rings, it solves the suspension problem perfectly. Double insulated so if you only have 2 core cable this is ok. Fits a 40mm shade hole
Cannot hold shades with a 29mm hole. If in doubt consult a qualified electrician.
