Tilt Guide for 1 x 4 Array
Tables 1 and 2 show tilt with lift points facing front and rear, located on outside truss rails. Four cabinets create a
180” array that results in all locations on a common line behind the center of gravity. Tables 3 and 4 show tilt with
lift points located on inside truss rails closer to the center of gravity resulting in a wider range of options. This is a
better choice. Position 1 does not allow clearance for shackle mount and is noted no connection (NC). Aim angle
options range from +lO” to -12”
