## Long description

THI LOCK REC AGRA-1 481Z-34802/C is a cylinder-less mortise replacement unit intended for mechanical door locking systems. Designed to be fitted into standard mortise cutouts, this mortise replacement provides latch and deadbolt functions where applicable and is supplied without a separate cylinder. The unit is finished in chrome, offering a corrosion-resistant surface suited for both interior and exterior door applications when a non-cylinder lock body is required.
Advantages
The cylinder-less design simplifies installation in applications where an external cylinder is not needed or where a separate locking mechanism is used. Chrome finish provides a durable, low-maintenance surface with moderate resistance to wear and environmental exposure. The unit is compatible with typical mortise preparations, allowing direct replacement without extensive door modification when dimensions match. Mechanical latch and deadbolt operation deliver reliable basic security and door retention functions in residential and commercial settings.
Suitable for
Replacement of existing mortise lock bodies in doors prepared for a cylinder-less unit
Interior doors in residential or commercial buildings that require latch and bolt functions without an integrated cylinder
Exterior doors where a separate locking solution or reinforced security system is used instead of a cylinder inside the mortise body
Key specifications
Type: cylinder-less mortise replacement unit
Finish: chrome
Functions: latch and deadbolt operation (where applicable)
Compatibility: designed for standard mortise cutouts and mechanical locking systems
Intended use: interior and exterior doors
How to use
Measure the existing mortise cavity and faceplate dimensions to ensure compatibility before installation. Remove the old mortise unit and fit the THI LOCK REC AGRA-1 into the prepared cutout, aligning the faceplate with the door edge and securing with appropriate screws. Connect the door handle or lever spindle through the designated follower and test latch and deadbolt movement to confirm smooth operation. As this unit is supplied without a cylinder, install any required external cylinder or separate locking components according to their manufacturer instructions, if applicable.
Usage recommendations
For best performance, verify door thickness and mortise measurements prior to purchase. Use corrosion-resistant fasteners for exterior installations and lubricate moving parts periodically with a dry lubricant to maintain smooth operation. When combining with separate cylinders or electronic locking modules, confirm mechanical compatibility and clearances to avoid interference with latch or bolt travel.
