In this section, you'll find the simplest constructions (climbing systems) we offer, which consist of only one rope line. These are usually chosen for narrow areas, when there is no space for multiple/parallel cables, or for their low cost mark. Vertical cables are almost always used in this case; single horizontal cables are seldom used, and are therefore treated as a special case. Single cable systems are suited for strong twining plants like wisteria. Learn more about plant characteristics in the climbing plants section of this website. Several single strands can be grouped next to each other; this is an alternative to the climbing systems in the 4000-er category or the 8010, if no networking and wire framework is desired for design reasons. If necessary, please also consult the planning guides. Note: without correct care or trimming, scratch marks can occur on walls with external thermal insulation composite systems (ETICS) as a result of high wind and twisting of the spindles during the initial development phase with single-wire systems.
