This is installed on the ridge board in the attic of a 50’s era built home. We could not trace the wire once it left the attic. The sheathing is braided fabric that is not fraying or heat degraded and the metal of this device is not rusted or damaged. The heating system of this home has been converted to electricity but was originally an oil fired forced air furnace system. This part may date from that time but its’ function is unknown.
Does anybody recognize or know what this is?
