Assemble lighting with standard thread size lamp pipe and couplings.
All thread pipe is universal in lamp fabrication as it is the back bone of many floor and table lamps. Lock nuts, bushings and spindles secure parts and join them together. Lamp pipe flange is a useful part enabling a lamp pipe to be attached to a wood surface. 1/8 IP, 3/8" diameter, and 1/4 IP, 1/2" outside diameter, are the two most common lamp thread sizes.
