UL-Approved Lamp Cord KnotComments (0)
This article is from Issue 61 of Woodcraft Magazine.
If you make lamps (or simply repair them on occasion),
it’s worth knowing how to make an
Underwriters Laboratories approved knot. All commercially sold lamps
include a UL-approved knot at the end of the electrical cord within the lamp
socket. It’s designed as strain-relief to prevent a yanked cord from
disconnecting from the socket, as the knot cannot be pulled through the socket
nipple. As shown in the drawing, it’s “knot” hard to tie, so why “knot” use it?
