Recommendations and installation instructions

  • The wire bed made of 3mm or 4mm thick stainless steel is the backbone of the system: wires must be installed twist-free and fixed only by using original GRIPPLE wire tensioners, that we also provide. These allow an easy adjustment of the tension without reducing the strength of the wire, as it might occur if using other common tensioners for fence building.
  • The stainless steel wire should at no point have contact with the greenhouse construction, in order to prevent contact corrosion.
  • Novavert offers specially designed accessories, that help avoiding cuts or damages of the drive wire or push-rods in stationary components and allow a durable function.
  • Maintenance: the HS² system parts should be regularly greased on the critical spots of the drive system, such as racks and pinions. The drive cables should be frequently checked. If you suddenly hear strange noises when opening or closing the system, give the matter your full attention and look for assistance, if needed. The profiles and sliding supports do not require any specific service. Do not attempt to perform any repair or maintenance on your own, please refer to experienced installing companies: this will ensure a long-term value retention of your investment.
