The all-rounder for individual requirements

Installation Housings XL-Series

Throughly thought through to every corner

Absolutely concrete-tight, mounted in seconds and numerous possible applications. With the new XL-Series installation housings, Primo has developed all-rounders that are perfect for mounting all special installation housings – from luminaires to loudspeakers to other built-in components. The modern membrane technology can be opened effortlessly with a cutter knife, the conduit grip ensures reliable strain relief and, thanks to the integrated conduit stop, bothersome and time-consuming rework is no longer necessary. The electrician thus saves work, time and money and is well able to meet the growing demands on the quality of installation work.
