Breakable Coupling - MR-F2 Breakable Coupling

  • ICAO

When approach lighting fixtures need to be installed at a certain height to compensate for the unevenness of the ground, ICAO recommends that such mounting systems be light and frangible. Up to 1,8 m from ground level, a 60 mm O.D. aluminum conduit, supported in a MR/F2 breakable coupling is the recommended solution. For installation heights above 1,8 m, approach lighting fixtures are mounted on frangible safety approach masts, type SM/A. ADB SAFEGATE’s Breaking Coupling are corrosion proof and UV resistant. Lightweight, yet sturdy, they are suitable for the most versatile mounting methods.
