Wherever you need to prevent annoying air circulation in your electrical installation—be it for energy efficiency reasons or because of requisite cleanroom or hygiene conditions—our cavity wall outlets with press-out membrane are the first choice. Pipes or tubes can be pressed through the membranes without additional tools, saving you even more time.
The E 4000 and E 4100 models have a raised, enlarged press-out membrane on the side for tubes up to 25 mm, which are ideal for prefabricated housing areas. It goes without saying that all models in this series are VDE-certified and tested in accordance with the ''blower-door test''. Use innovation from F-tronic.
