Channel magnet 40 x 40 x 4 mm

with countersunk borehole, in U-shaped steel profile
promptly deliverable


This channel magnet is a square flat countersunk block magnet with two boreholes, embedded in a U-shaped steel profile. The steel significantly reinforces the magnet's adhesive force at direct contact and at the same time protects it from blows.
Its thickness of only 4 mm allows for hanging up signs, tools, etc. discreetly. It is especially suitable for carpentry, kitchen/booth/store construction, and signage technology.
