The Ergo-Schnitt telescopic poles are made from glass fibre braid (GFB) covered with a layer of resin. The material offers 5 x higher resistance against breaking compared with aluminum. No corrosion occurs to the GFB and it is very low wear-and-tear. GFB does not conduct electricity when it is clean and dry. This has been confirmed and certified by an accredited inspection laboratory. Ergo-Schnitt telescopic bars can be steplessly set to any height. A tensile strength of 75 kg is attained via an eccentric lever which can be set with the opposite nut (left-handed thread).
