This mortise door lock is designed for left-swing doors and provides latch and bolt functions according to the model specification.

## Long description

Left-handed mortice lock LOB 52.783D is a compact lock body designed for installation into a door cut-out on left-swing doors. Intended for residential and light commercial use, this mortise door lock integrates latch and bolt functions in a concealed format and is compatible with standard mortice door handles and cylinders. The product is suitable when a recessed locking mechanism is required to preserve door aesthetics while providing secure latching and deadlocking according to the model's configuration.
Advantages
The mortice lock offers a recessed installation that keeps the lock mechanism hidden inside the door, reducing visible hardware and improving appearance. Its left-handed configuration ensures correct operation for doors that open toward the left. The combination of latch and bolt functions in one unit simplifies installation and reduces the need for separate locking components. Constructed for everyday residential and light commercial use, it provides reliable mechanical performance when fitted with compatible handles and cylinders.
Suitable for
Left-swing residential interior or exterior doors
Light commercial doors such as small offices or service rooms
Doors requiring a concealed mortice lock body for aesthetic or security reasons
Key specifications
Handing: left-handed configuration for left-swing doors
Function: combined latch and bolt mechanism
Installation: mortice/recessed fit into door cut-out
Compatibility: designed for standard mortice handles and separate lock cylinders
Application: suitable for residential and light commercial doors
How to use
Prepare the door by measuring and cutting the appropriate mortice cavity according to the lock body's dimensions. Insert the LOB 52.783D lock body into the cavity, align it with the faceplate and fix it to the door using appropriate screws. Fit matching handles and a compatible cylinder through the door and connect them to the lock mechanism. Check operation by turning the handle to retract the latch and by operating the key or thumbturn to extend and retract the bolt. Ensure that strike plate alignment in the door frame allows smooth latching and secure deadlocking.
Usage recommendations
Use appropriate corrosion-resistant screws and a strike plate matched to the lock for reliable long-term function. Verify handing before installation and test the lock operation several times after fitting. For exterior doors, combine the lock with a weather-resistant cylinder and maintain moving parts periodically with a dry lubricant to prevent buildup.
