Concrete junction box Prefix®

Concrete building boxes with Prefix® installation technology and two integrated front parts ensure an additional improvement during fitting to the formwork. The Prefix concrete building boxes can be pre-fitted using spring-loaded installation clamps. A peripheral, pronounced corrugated profile along the installation clamps for use with tie wires prevents slipping during fixing. If extreme loads are expected, additional opportunities for attaching tie wires exist along the mounting profile. Together with a more compact form, this simplifies working, which ensures exact positioning of the box and a clean wall appearance. Fast, easy installation directly onto the opposing formwork without support element and abutment Prefixing using Prefix® installation technology leaves both hands free for attaching with wires A pronounced corrugated profile and additional fixing opportunities for secure fixing using tie wires Suitable for 20-60 mm concrete covers For facing concrete installation to the opposing formwork Can be combined to create standardised stable multiple combinations
