Handy board wiper Ø 5 cm with a Finepoint marker "S". Due to its small size, this magnetic board wiper is hardly noticeable on whiteboard boards. The pen is always tidy thanks to the existing clamping device on the back of the wiper. The font color is black and can be dry-erased. Suitable for white blackboards. Font size: Ø 1.5 - 2.0 mm
Determination of the magnetic force
The adhesive force of our magnets is determined at room temperature on a polished plate made of steel S235JR (ST37) with a thickness of 10 mm by the vertical withdrawal of the magnet (1kg ~ 10 N).
A different value down to -10% compared to the specified value is possible in exceptional cases. In general, the value is exceeded.
Please note that for thinner, painted and not absolute plan undergrounds the adhesive force represents only one raction of the specified values.
