STANDARDISED SPECIAL INSTALLATION HOUSINGS
The clever alternatives – Standardised Special Installation Housings
Tinkering belongs to yesterday! In order to facilitate the creation of recesses in cast-in-place concrete, Primo has developed practical and Standardised Special Installation Housings. This eliminates the time-consuming creation of individual wooden or foam polystyrene recesses for the electrician. In addition, the Primo products can simply be recycled after concreting and are therefore more sustainable than the classic methods. The Primo Ventilation Sleeve is ideal for ventilation recesses, while the Primo Schalfix is recommended for all other areas of application.

Innovative and efficient
With the use of the Primo Ventilation Sleeve, installers have a time-saving of up to 30 minutes per recess compared to the use of conventional methods. The Primo Schalfix even saves up to an hour of time compared to the classic recess. Both Schalfix sizes are made of plastic and therefore are completely weatherproof and pH-neutral. The polypropylene Ventilation Sleeve is heat-resistant from -5 °C to 100 °C and is halogen-free. All Special Installation Housings are recyclable.
