Elizabethton is a smaller stretch of the service area, about 5,953 households, which means the cable calls we get here cluster around a narrower band of houses than you'd see in a bigger town. Most of what's standing went up around 1964, give or take, and that's the number that actually matters for cable work. A door that age is usually on its second or third spring set by now, but the original cable drums and the stamped-steel tracks that came with them often never got touched. Those drums wear a groove over decades, and once the groove deepens, the cable starts riding wrong and frays at the same spot every time. We're coming out from Johnson City, about 8 miles off, so when we take a call here we already expect a 1960s-era door with that drum wear rather than a newer roller system. The cold-moderate climate this part of Tennessee sits in doesn't help - temperature swings make the galvanized coating on an older cable brittle faster than it would wear in a milder spot, and once that coating cracks the strands underneath start rusting from the inside out, which you can't see until the cable snaps.
