The Universal Solution: Mortise Smart Locks for Wood Doors with Multi-Lock Body Compatibility

Before diving into the solution, it's essential to understand the problem. A wood door's lock mechanism is defined by two critical measurements:

1. Backset: The distance from the edge of the door to the center of the bore hole for the lock (commonly 60mm or 70mm).

2. Lock Body Size: The physical dimensions of the lock case that fits inside the door. Common standards include:

   • 6068: 60mm backset, 68mm center-to-center screw hole distance

   • 5572: 55mm backset, 72mm center-to-center distance

   • 6085: 60mm backset, 85mm center-to-center distance

For years, installers faced a frustrating choice: either customize each door to fit a standard smart lock or stock multiple lock models for a single project. Both options increase costs, complicate logistics, and delay installation timelines.

The LaDing Solution: One Lock, Endless Possibilities

Our engineering team recognized this industry-wide pain point and developed a smart lock system built around universal adaptability. Here's how it works:

1. Fully Integrated Lock Mechanism: Strength Meets Flexibility

Unlike many smart locks designed primarily for retrofit plates or specific door preparations, our fully integrated lock mechanism is engineered specifically for the depth and structure of wood doors. This design ensures:

• Superior Stability: The lock mechanism sits securely within the door's core, preventing wobble or misalignment over years of use.

• Enhanced Security: A fully integrated installation provides greater resistance to forced entry compared to surface-mounted alternatives.

• Aesthetic Integrity: The lock integrates seamlessly with the door's profile, maintaining its visual appeal.

2. Multi-Lock Body Compatibility: The Game-Changer

The true innovation lies in our lock's ability to accommodate multiple standard lock body sizes within a single smart lock chassis. Whether your project requires:

• 6068 (Common in residential apartments)

• 5572 (Frequent in commercial offices)

• 6085 (Used in thicker, high-security doors)

• And various other regional standards

Our smart lock platform includes adjustable mounting brackets and interchangeable components that allow installers to adapt the lock to the existing door preparation. This means:

✅ Simplified Inventory: Stock one smart lock model for all your wood door projects.
✅ Reduced Installation Time: No need for door modifications or custom adapter plates.
✅ Lower Costs: Fewer SKUs mean better volume pricing and less capital tied up in inventory.
✅ Consistent User Experience: Tenants and users enjoy the same premium smart lock interface across all units.

Real-World Applications: Where Our Universal Lock Excels

1. Large-Scale Apartment Developments

Imagine a new apartment complex with 500 units. Doors arrive from multiple manufacturers, each with slight variations in lock body specs. Instead of juggling three different smart lock models, you deploy a single LaDing lock across the entire property. Installation is faster, training is simpler, and future maintenance is streamlined.

2. Hotel Renovation Projects

Older hotels often have a mix of door types and lock preparations accumulated over decades of expansions. Our universal lock allows renovators to upgrade all rooms to modern smart access without customizing each door—saving weeks of construction time.

3. OEM Door Manufacturing

For door manufacturers, offering a "smart-ready" door has never been easier. By partnering with LaDing, you can pre-install our lock platform, knowing it will accommodate your standard lock body sizes. This adds significant value to your product line without complicating your production process.
