The table above shows the application of these sockets as lifting points. These tables show a typical situation and you should check your situation is within these parameters. If your situation falls out of these parameters, please contact CFS for bespoke advice and calculations. Where two or more sockets are in use, they should be spaced ataminimumof2xCmin apart. Some Axial Loads require reinforcement as shown below. Please ensure that the reinforcement touches the end plate of the socket. Easy to install with no anchorage reinforcement
