Dorfit Mortise Lock, 8545E-SN, Zinc Alloy, 85MM Hole Dia, 45MM Backset Size, Satin Nickel

The Dorfit Mortise Lock, 8545E-SN is a robust and reliable mechanical locking solution designed to provide secure and smooth door operation for a wide range of interior and exterior applications. Engineered for strength, durability, and compatibility with standard door fittings, this mortise lock body delivers long-lasting performance in residential, commercial, and light industrial installations where dependable security and precise functionality are essential. At the core of this mortise lock is a high-grade zinc alloy construction, chosen for its excellent balance of mechanical strength, corrosion resistance, and wear-resistance properties. The zinc alloy lock body is built to withstand frequent daily use while maintaining structural integrity and smooth mechanical motion over time. Its satin nickel finish not only enhances visual appeal with a muted metallic sheen but also provides additional surface protection against rust and oxidation, ensuring consistent performance even in humid or high-traffic environments. The lock is designed around standard 85 mm hole center spacing and a 45mm backset, which are widely accepted dimensions for mortise lock installations. These standardized measurements allow for straightforward fitting into prepared door cutouts and compatibility with many existing door furniture setups. The mortise configuration means the lock body is recessed within the door edge, resulting in a neat and flush-fitting appearance that maintains the aesthetic integrity of wooden, metal, or composite doors. This mortise lock is suitable for use in wooden and metal doors, making it versatile across different architectural contexts — from entrance doors to room partitions and access points where secure closure is required. Its internal mechanism is engineered to facilitate reliable latch engagement and disengagement, ensuring smooth door operation with minimal effort while contributing to a secure fit that resists accidental openings.
