Factory galvanized cable
The median home here was built around 2002, which means most of what we're pulling cable off is factory-installed galvanized aerospace cable on a standard extension or torsion system, not the older twisted stuff you find in houses from the 1960s and 70s elsewhere in the service area. That matters for cost: newer cable drums and end fittings are still in production, so you're not paying a premium for a part nobody stocks.
