The mounting studs have both female and male threads. They have never been used. These are the same a matched pair in every way, except if you look closely the finish is just slightly different. One looks to be chrome plated, having the distinct silvery color of chrome.
The other one has a slightly warmer tone, and looks to have a nickel colored finish. It may just be luster loss from age? But we want you to know.
They are the same in every other way. These measure 5 across mounting hole center to hole center. They are 1 wide at the widest points.
Application : I'm not sure of the exact application. Please check the measurements and do your own research. Condition : These are in very good condition. They are nice and shiny with a few light surface scratches and dings here and there. The threaded mounting studs look very good.There are a few small spots of surface finish loss revealing what looks to be brass underneath. This is a nice solid pair.
