Adjustable Lamp Fixture Stems support single lamp sockets or socket clusters. 4" adjustment provides flexibility in determining best height for lamp shade placement. Regulate height by loosening thumb screw, sliding stem to best position and then re-tighten thumb screw.
Almost tossed out a lamp that sat broken for years, but I liked it enough to try one more time to find a part - difficult when I didn't know the name of the part I was searching for. I finally found it at Paxton. I have a working lamp again and am so glad I waited all those years. Thanks, Paxton!
