A Levelling Pole and Spanner are provided (free of charge) on all Retention Socket orders. This ensures the vertical installation of the Retention Sockets at Civils stage. It also enables Civils works to be completed without the need for the Street Furniture to be on site. This eliminates the risk of damage to the Street Furniture. Contractors must note that prior to leveling, the levelling pole must be locked in place with the securing bolt / bolts located in the side chamber of all Retention Sockets. This is done with the spanner provided. Failure to lock levelling pole in place may result in Retention Sockets being installed off line.
