Product details


DORMA CORE is characterized not just by design and quality but also by variety. The CORE lever handle series encompasses a wide range of popular lever handle styles for the project/contract build sector. CORE fittings are available in fire-resistant and smoke-control versions, and models for emergency exit devices are certified to EN 179.


With the CORE series of lever handles, DORMA demonstrates that economic, cost-efficient solutions can effectively meet standard design specifications throughout the build. The CORE lever handle series is thus particularly suitable for use on functional project/contract doors.


CORE fittings are a reliable solution fully in keeping with the DORMA quality standard. They are supplied as complete sets for timber/wide stile doors with round roses and escutcheons or short oval backplates, and as single-handle half sets for narrow stile doors with narrow roses and escutcheons.
