IPL group's Retention System™ sockets were used for the installation of traffic signals on Hannoversche Straße, located in Berlin's university and museum district. The RS140 socket foundations were completed before the traffic signal pole was brought to the site. Electrical cables were pulled up through the RS socket bend, and the pole was then locked into place.

IPL group's robust and versatile RS socket foundations not only simplify installation practices but also assist asset owners and operators with management and maintenance requirements. Should the pole become damaged in the future, it can be replaced without excavation, which reduces maintenance costs and disruption for road users.
