Round Rose Lever Trim TKAMRR9200

Product Description

Our ANSI Grade 1 mortise lock is a heavy-duty commercial mortise lock designed for commercial doors, institutional buildings, and high-traffic public facilities. As a reliable mortise lockset for commercial and architectural hardware applications, it combines outstanding durability, high load resistance, secure emergency override, and precision-engineered internal components. It is an ideal high-security mortise lock solution for office buildings, hotels, schools, hospitals, apartments, and other demanding projects requiring long-term performance and dependable access control.

Key Features

1. Exceeds ANSI Grade 1 Durability Requirements
   Our ANSI Grade 1 mortise lock is engineered as a heavy-duty commercial mortise lock for high-traffic commercial, institutional, and public building applications. With a mechanical lifecycle of over 2,000,000 cycles, this high-security mortise lock significantly exceeds ANSI Grade 1 durability requirements, delivering exceptional long-term reliability for office buildings, hotels, schools, hospitals, apartments, and other demanding commercial door environments.
2. Latch Bolt Load Resistance up to 10,000N
   The latch bolt is designed to withstand a compressive load of up to 10,000N, making this commercial mortise lockset ideal for demanding applications where high closing force, repeated operation, and structural stress are expected. It is a robust ANSI mortise lock solution for heavy-duty doors in commercial and institutional projects.
3. Enhanced Emergency Override Structure
   This ANSI/BHMA mortise lock features an advanced internal mechanism that allows the exterior cylinder to override the interior knob even when it is being held. This provides secure and reliable emergency access, making the lock suitable for high-security commercial door lock applications where safety, controlled access, and dependable override performance are essential.
4. Precision Investment Casting for Critical Components
   The latch bolt, deadbolt, and auxiliary bolt are manufactured using precision investment casting rather than conventional powder metallurgy. This improves the structural strength, wear resistance, and long-term durability of the mortise lock body, making it a premium commercial mortise lockcase for demanding building hardware applications.
5. High-Durability Lever Spring Mechanism
   The lever return spring assembly is produced using precision casting technology instead of conventional zinc alloy construction. This helps prevent fatigue, deformation, and aging issues often seen in standard market products, ensuring smooth lever return, stable operation, and long service life for heavy-duty mortise lock hardware used in commercial buildings.
