So, I have posted this fixture before, (just finally brought it home to get in line for a service call.) A question came up while looking at it - first of many I'm sure given the other similar Major fixture I just completed. This fixture has a handle attached to the knob on the left side but not the right side. Why is this? Why not also the right side? Why is such a thing not found on say modern Lekos - what advancement in how it's done while not completely, normally makes this concept not necessary?
