The Elite EDGB45KW key-wind centre gearbox is a replacement centre component, not a complete multipoint locking strip.
The retained reference is EDGB45KW, while the existing product label and supplier variant description state 35mm. The supplied backset must be confirmed from the actual case or exact original drawing; the code suffix is not measurement proof.
DGS describes key-wind operation on specific complete Elite locks, but an exact spare-case crosswalk and key-turn count have not been established for this reference. Do not substitute an automatic gearbox or assume a two-turn-plus-extra-turn sequence.
Match the exact original case and lock generation, backset, spindle arrangement, case outline, drive connections and retaining fixings. Matching the brand or a single measurement does not establish a direct replacement.
A centre-case repair can retain the locking strip only when the replacement is an exact match and the strip, remote locking points and frame keeps remain serviceable. Have the fault and the complete assembled lock checked before assuming that the gearbox alone is sufficient.
