Flush-mounted junction boxes for flexible corrugated plastic conduits (KRFG)

Flush-mounted junction boxes with KRFG technology are specially optimised for wiring using KRFG (flexible corrugated plastic) conduits The specially designed conduit inlets can resist the highest pull-out forces. The conduits can also be secured using rebar ties or cable ties. This enables the electrician to have confidence that the conduits will still be in place after concreting.
