Mechanical Data
The front panel of the SAFETY BOARD is made of 5 mm thick
Laminate, matt blue in color with white engraving representing
the built-in function groups.
The rear of the Board is protected with a gray plastic cover.
Its shape allows the Board to be placed at an ergonomically favorable
angle for example on a table.
