Foam Bars
Figure 4-4 Foam bars
The foam bars (order code 3122 785 90580) can be used for
all types and sizes of Flat TVs. By laying the plasma or LCD TV
flat on the (ESD protective) foam bars, a stable situation is
created to perform measurements and alignments. By placing
a mirror under the TV, you can easily monitor the screen.
