Remedial wall tie mechanical VBS-M

The quick façade repair for two-leaf cavity walls

The fischer remedial wall tie VBS-M is suitable for the renovation of two-shell masonry. Above all, it is used for the subsequent application of heat insulation or to secure a suspended, rear-ventilated façade. Thanks to the two expansion zones of the plug, the cost-effective solution enables the safe connection of the facing masonry and outer shell. The low anchorage depth of just 50 mm also enables fast and cost-effective installation in stone and in bed joints. The slim plug edge and head enable a flush installation or a deeper installation with no annoying projection. The drill hole can be retrospectively grouted so that it is no longer visible.

Product Description

  • The approved fixing in stone and in joints from at least 50 mm facing masonry provides a high degree of flexibility and security.
  • Use in joints and with a low anchorage depth of just 50 mm allows for a quick and economical installation.
  • The small anchor rim and screw head allow for a surface-flush or deep-set installation.
  • The drill hole can be retrospectively sealed so that it is no longer visible in the façade.
  • A drip coil prevents condensate running into the load-bearing layer, thus preventing frost and corrosive damage.
