What is a utility and control-cabinet key?
A utility and control-cabinet key is a pocket-sized tool, usually with multiple head profiles (shapes), that can be used to unlock service cabinets, turn switches on and off and regulate valves.
They are designed to be a handy tool to have around and can be used for multiple purposes.
In the home, they are used to unlock gas and electricity meters or to bleed (release unwanted air from) central heating radiators, but the majority of uses occur in the services or facilities industries (e.g. sanitation).
Utility and control-cabinet keys are also known as service-cabinet keys, spider keys, universal utility keys, services utility meter keys or switch-cabinet keys.
