1. Mortise Preparation
Mark the Door: Use the lock body as a template to mark the depth and height on the edge of the door.
Cut the Slot: Use a mortising machine or a drill and chisel to create the internal pocket where the lock case will sit.
2. Fitting the Lock Body
Insert the Case: Slide the stainless steel lock body into the prepared slot to ensure it sits flush against the door edge.
Secure Faceplate: Use the provided heavy-duty screws to fix the faceplate firmly to the side of the door.
3. Component Alignment
Install Cylinder and Spindle: Insert the key cylinder through the designated profile hole and slide the square spindle through the handle hub.
Mount the Strike Plate: Align the strike plate on the door frame with the three deadbolts and the latch to ensure smooth locking engagement.
1. Daily Operation
Retract Latch: Turn the door handle downward to retract the top latch and open the door.
Engage Deadbolts: Turn the key or thumb-turn two full rotations to extend the three reinforced deadbolts into the door frame for maximum security.
Automatic Latching: When closing the door, the spring-loaded latch will automatically engage to keep the door shut even when the bolts are not thrown.
2. Maintenance
Check Alignment: Ensure the three bolts align perfectly with the strike plate on the door frame to prevent friction or jamming.
Surface Care: Wipe the stainless steel faceplate with a damp cloth to remove fingerprints and prevent surface oxidation.
Lubrication: Apply a dry graphite lubricant to the keyway and a small amount of grease to the bolts once a year to maintain smooth mechanical movement.
1. Triple-Bolt High Security
Reinforced Deadbolts: Unlike standard locks with one small bolt, this model features three heavy-duty deadbolts that distribute the force of an attempted break-in across a larger surface area.
Anti-Saw Protection: The hardened stainless steel bolts are designed to resist cutting and sawing, providing a formidable barrier for perimeter doors.
2. Marine-Grade Stainless Steel 304
Corrosion Resistance: The entire lock case and faceplate are constructed from Grade 304 stainless steel, making it immune to rust and oxidation in humid or coastal environments.
Long-Term Aesthetics: The brushed steel finish maintains a professional, high-end look without the pitting or peeling common in cheaper zinc-alloy lock bodies.
3. Universal Compatibility
European Standard (DIN): This lock body follows standard architectural dimensions, making it a perfect smart lock body replacement or an easy upgrade for existing European-style doors.
Fire Rated Safety: Designed to meet strict safety codes, the all-metal construction ensures the lock remains functional even under high-heat conditions during an emergency.
