The key cylinder of Gainsborough’s 3400 mortice lock is located below the handle for easy operation.
Designed and manufactured in Australia, the Gainsborough 2000 series (23 mm backset for narrow stile doors) and 3000 Series (60 mm backset) heavy-duty mortice locks feature the key cylinder below the lever for ease of operation. The location of the cylinder under the lever (rather than above it) provides a more convenient position in which to lock or unlock with the key.
Gainsborough also offers the 7000W series levers and knobs on long plates to suit the 3000 series mortice locks; and the 7000N series levers on narrow, long plates to suit either 2000 or 3000 series mortice locks.
