Triangle Keys

Triangle keys operate quarter-turn locks with a triangular spindle, used on electrical and utility cabinets, meter boxes, service doors, lift panels, railway carriage doors and some gas and water covers. They are sized by the triangle measurement, often in millimetres.Before ordering, measure the triangle in the lock and check whether you need a male key that fits into a socket or a female socket that fits over a pin. Multi-purpose utility keys combine several triangle and square sizes if you are unsure.Triangle keys should be used for authorised or legitimate access only, on equipment you own or are responsible for. Railway, utility and network operator equipment must be left to authorised staff. Maintenance teams can order in quantity through Key Factory for Business.
