5. Array configurations ___________________________________________ 

 

 
GRD24B options 
 

The schematic picture below shows the possible array hang options a-d and stack arrangement e with LR24.  
 

As stated earlier, the array angles can be determined through the Alcons Ribbon Calculator™ simulation program. 
When ground stacking (e), ensure that the centre of gravity is well within the grid’s base area. 
single point hangs can be done but are not recommended with LR24 due to safety and array building complications.
