The Mansfield genuine 39SB (Sicilian bronze) trip lever is an all metal lever designed for the models, 108, 192, 3106, 3987, and 2987. This lever will mount on the side of the toilet tank unlike most levers that will mount on the front. The lever comes complete with the lock nut, which is reverse threaded. Reverse threads mean you turn it to the left to tighten, and right to loosen.
