Airfield lights are mounted on frangible couplings which are designed to break at a defined force. Their use protects the integrity of the unit itself and minimizes damage to the object that strikes it.
Important Features
Couplings have a designed yield point, therefore they should be used with the light they are designed for. Failure to do so will result in the coupling not working properly
Frangible couplings allow repairs to take place in minimal time.
