Opened in 2011, the University of Philadelphia's Penn Park features 24 acres of athletic fields, open recreational spaces, and a new pedestrian gateway uniting West Philadelphia with Center City. A major feature of Penn Park is its commitment to sustainability in both construction and operation.

With a focus on future management and maintenance needs, RS115 sockets were used for the installation of removable bollards on pedestrian and vehicular access routes. When required, the bollards can be removed and the access routes can be opened and controlled by authorised university personnel. Retention System™ sockets provide the foundation for an efficient, sustainable infrastructure design. They deliver time and cost savings, and offer safe and environmentally sound solutions for the installation, maintenance, and replacement of post-based structures.
