We disassembled the switches, then cleaned and lubed them, and they are guaranteed to work smoothly and correctly. However, we recommend that a wall switch be the principal on/off mechanism. This kind of pull chain socket is no longer made and if one breaks you have to salvage another one to repair it... However, the pull chains give that 1930's look and if you are restoring an older home, these might be perfect. Everything has been tested and is guaranteed to work correctly.The mounting hardware is included (nickel plated mounting nuts, threaded nipples, crossbars). Dimensions: 8-1/2" high (to end of chain), 4-1/4" wide, project 4 from the wall. Just notify us within 30 days of receiving them.
