Product Details

Exceeds ANSI Grade 1 Durability Requirements
Our ANSI mortise lock significantly surpasses ANSI Grade 1 standards, achieving a mechanical lifecycle of over 2,000,000 cycles, ensuring exceptional long-term reliability for high-traffic commercial applications.
Latch Bolt Load Resistance up to 10,000N
The latch bolt is engineered to withstand a compressive load of up to 10,000 Newtons, making it suitable for demanding environments where high closing force and structural stress are expected.
Enhanced Emergency Override Structure
The lock features an advanced internal mechanism design that allows the exterior cylinder to override the interior knob even when it is being held, ensuring secure and reliable access control under emergency or high-security conditions.
Precision Investment Casting for Critical Components
The latch bolt, deadbolt, and auxiliary bolt are manufactured using precision investment casting, delivering superior strength and structural integrity compared to conventional powder metallurgy processes commonly used in the industry.
High-Durability Lever Spring Mechanism
The lever return spring assembly is produced using precision casting technology, eliminating material fatigue and aging issues commonly associated with zinc alloy components used in standard market products. This ensures consistent performance and long-term operational stability.
