This specialized lock combines elegant design with robust functionality, providing reliable protection while complementing the natural beauty of wooden doors. Available in two standard sizes (60mm and 70mm), it offers versatility across various door thicknesses and styles, making it a preferred choice for both new installations and retrofits. Its precision-engineered components ensure smooth operation and long-term durability, making it ideal for residential and light commercial wooden doors where aesthetics and performance are equally important.

This mortise lock features a high-quality zinc alloy construction that balances strength, durability, and workability. The alloy formulation provides excellent resistance to corrosion and wear, ensuring reliable performance even in varying humidity conditions that can affect wooden doors. The zinc alloy components undergo a multi-step finishing process that enhances both their appearance and resistance to environmental factors, ensuring the lock maintains its functionality and aesthetic appeal over time.
Available in two standard sizes, 60mm and 70mm, this mortise lock accommodates different door thicknesses and stile dimensions commonly found in wooden door construction. The 60mm size is ideal for standard interior wooden doors, while the 70mm option provides enhanced security for exterior wooden doors and thicker door constructions. This size versatility ensures proper fit and function across a wide range of wooden door applications.
The lock incorporates a dual-bolt mechanism featuring both a spring-loaded latch bolt for daily use and a deadbolt for enhanced security when needed. The deadbolt engages deeply into the strike plate, providing robust resistance against forced entry attempts. Both bolts are precision-machined to ensure smooth operation and positive engagement, with the latch bolt featuring adjustable backset options to accommodate different door preparations.
Engineered with installer convenience in mind, this mortise lock features pre-machined components and standardized dimensions that simplify the installation process. The lock body includes clear marking for accurate positioning during the mortising process, reducing installation time and ensuring proper alignment. The package includes all necessary hardware, including strike plates and mounting screws specifically selected for wooden door applications.
The Zinc Alloy Mortise Lock is specifically designed for use with wooden doors in both residential and light commercial settings. Its 60mm configuration excels in interior wooden doors such as bedrooms, studies, and dining rooms where privacy and aesthetics are priorities. The 70mm version provides enhanced security for exterior wooden doors including front entry doors, garden doors, and wooden gates where improved protection is required. This lock is particularly well-suited for use with solid wood doors, engineered wood doors, and wooden door frames in heritage properties, modern homes, and boutique commercial establishments where maintaining the natural beauty of wood is important.
The primary difference is the overall length of the lock body, which corresponds to different door thicknesses and security requirements. The 60mm lock is typically used for standard interior wooden doors (35-45mm thick), while the 70mm lock is designed for thicker exterior wooden doors (45-55mm thick) where additional security and longer bolt throw are beneficial.
The lock is designed for use with most solid wooden doors and high-quality engineered wooden doors. It is not recommended for use with very thin hollow-core wooden doors or doors with insufficient stile width to accommodate the mortise cut. We recommend a minimum stile width of 80mm for proper installation and functionality.
Installation requires standard woodworking tools including a drill, chisel set, tape measure, square, pencil, and screwdrivers. A mortise gauge can be helpful for marking the cutout area accurately. For best results, we recommend using sharp wood chisels to ensure clean cuts in the wooden door.
Yes, this mortise lock is compatible with most standard door handle sets and knobs designed for mortise lock applications. It features a standard spindle hole that accommodates common handle configurations, allowing for customization of the door's appearance while maintaining the lock's security features.
Regular maintenance ensures optimal performance. Every 6 months, apply a small amount of dry lubricant to the moving parts through the keyhole and handle spindle. Inspect the strike plate periodically to ensure it remains securely fastened and aligned with the lock bolts. In humid environments, check annually for signs of corrosion and address any issues promptly to maintain smooth operation.
