Magnetic contacts are basic elements of a perimeter protection system. Large  B-4L tight magnetic contacts in a metal housing are designed for surface mounting. The metal screen protects the wiring against damage, which makes these contacts a perfect solution for locations particularly vulnerable to sabotage attempts or mechanical exposure. These contacts are screwed to a surface and provide an ideal solution for garage gate installation.
