    Maybe the stringer spacers are polymer though. Like those separation bars you see on residential power lines

      Maybe they’re polymer but they look pretty metallic and there’s an awful lot of them. Plus if the stringers are under enough tension for a full grown man to climb them they wouldn’t need separators.
