FIELD: conductors.
SUBSTANCE: group of inventions relates to methods for fastening one or two lightning protection down conductors to a standing seam of a seam roof at a given height using a down conductor holder. The down conductor holder contains a clamp for fixing the down conductors, vertical supports and fasteners.
EFFECT: possibility of mounting down conductors at a given height from the roof, above the roof seam, and ease of installation, with the possibility of mounting the down conductors in an upper well-observed position and selecting a range of a given height from the roof.
