Constructed from a variety of materials and featuring a polished brass sheen, these robust double cylinder entrance mortise locksets are tailored for external doors. Their design seamlessly integrates with the antique hardware of interior doors, ensuring your home's security remains unimpaired. These locksets are compatible with doors measuring 1-3/8 to 1-3/4 inches in thickness, and by utilizing Segal keyway lock cylinders, they marry the nostalgic charm of vintage hardware with contemporary security standards.

The knobs, made of diecast and reinforced steel, exude a refined, wrought solid brass finish that adds a touch of elegance. Accompanied by a gray plastic dust box for installation under the strike plate, these locksets boast enhanced security through their split spindle knob system. The exterior side houses the female-threaded half with cross-pin insert, while the interior side inserts the male-threaded half, preventing exterior tampering. Fastened to the spindle halves with set screws on each knob shaft, the knobs' handedness is reversible, as indicated in the provided instructions. Alternatively, pre-assembled locksets with opposite-handed latches are available for immediate installation.

Each lockset comes equipped with detailed and easy-to-follow installation guidelines, ideal for left-handed entry doors. This particular model is specifically designed for doors ranging from 1-3/8 to 1-3/4 inches in thickness, harmoniously complementing the vintage interior aesthetic.
