ANSI Door Handle Lock is a type of door hardware that complies with performance standards defined by American National Standards Institute, ensuring consistent quality in strength, durability, and security. These locks are commonly evaluated under grading systems such as Grade 1, Grade 2, and Grade 3, which indicate different levels of usage intensity. Widely used in commercial and residential projects, ANSI-certified door handle locks provide dependable operation, standardized dimensions, and compatibility with various door configurations and hardware systems.
Engineered for durability, security, and consistent performance across residential and commercial applications.
Flexible options available for wholesale, project supply, and OEM/ODM requirements.
The Entry Door Lever with Deadbolt (Model DDLK009) delivers a reliable combination of access control and reinforced security for residential and light commercial applications. This configuration integrates a smooth-operating lever handle with a high-security deadbolt system, ensuring both convenience and protection in daily use. Engineered to meet ANSI and UL 10C standards, it supports demanding environments where durability, fire resistance, and consistent performance are critical. Its stainless steel bolt with a 1/2 inch throw enhances resistance against forced entry, while the internal mechanism supports over 800,000 usage cycles, aligning with ANSI Grade 1 performance expectations. The latch and strike system is optimized for stable installation across standard door preparations, maintaining alignment and reducing long-term maintenance issues.
