The lamp finials offered on this web site have a 1/4-27 thread that fits on a standard lamp harp. If the fitting is different it will be noted in the description as 3/8" or 1/8ip. (They are the same size only stated in the language of a plumber and an electrician) Reducers and Nozzles can be ordered to convert threads to the desired size.
