CODELOCKS CL4020 Battery Operated Digital Lock

The Codelocks CL4020 is a high-quality, battery-operated electronic digital lock designed for low to medium traffic areas, suitable for both indoor and outdoor applications. This euro profile mortice sash lock features a deadbolt and latchbolt, complete with a double cylinder to control the deadbolt and retract the latchbolt. When the deadbolt is locked, access is denied to standard code users, while the key override remains available for management functions such as security and cleaning.

For added safety, the split follower allows the inside lever handle to retract both the deadbolt and latchbolt, preventing accidental lock-ins. This lock is non-handed and fully reversible, making it suitable for doors hung on either the left or right.

Depending on your requirements, this lock is available in fire-tested and non-fire-tested versions, with weights ranging from 3.053kg to 3.4kg. Please select your preferred fire rating, manufacturer reference (CL4020 or CL4020L SS FKP), and barcode option from the selections below.
