The installation in Edinburgh of traditional cast iron decorative lighting columns was restricted in some locations due to the proximity of kerbside services and cellars. A shallow depth RS250 Retention Socket was designed and engineered for this project. It incorporated four 50mm cable ports at the base of each Shallow Foundation Retention Socket for the required ducting. The root of the lighting column was then reduced to the specified depth of the Retention Socket.
The columns were then easily installed and secured in to the shallow depth Retention Sockets. The use of Retention Sockets for this scheme ensured the installation was easier and problem free compared to traditional methods.
