Boon Edam announced that The River Building, a commercial space located in London, has installed an array of slim Speedlane Swing optical turnstiles to control entry without being obtrusive as part of its office space renovation project. The River Building is nestled in the heart of London, sitting comfortably between London Bridge, St. Paul’s and Bank. The location is located just a few miles from the city’s underground subway system known as “The Tube”.
