The expensive magnetic system can be reused. A new localizing number can be purchased at a 50% discount. Any sequenze of self-adhesive numbers (between 1 and 999 in black or white) can be affixed to the magnetic box, by either you or us (at additional charge). Individual localization supports can be subsequently ordered for the serial price. You may add your company's or the carmanufacturer's logo onto the localization-number supports. The signal colors we have in stock are: yellow, red, blue, green, orange, white. If you do not want to stack your number boxes, the work control-board is the best storage place. The self-adhesive triangle overlays are scratch and gasoline resistant. There is room for 32 number boxes on every board. Overlays are available with the number 1 to 256 in steps of 32 (1-32, 33-64, 65-96,...). The heading "work control-board" is also available in other languages.
