Dorfit Rim Lock, DT6301, Iron, 60MM Backset Size, Painted Steel

The DT6301 Rim Lock features a dependable latch and deadlocking mechanism that engages solidly when the door is closed and locked. The mechanical components inside — crafted from durable metals — are designed to operate smoothly without excessive friction or play, ensuring reliable everyday performance whether the door swings infrequently or is used continuously throughout the day. The interior side typically incorporates a turn-knob or thumb-turn mechanism that allows quick manual locking and unlocking from inside, while the exterior may be fitted with a key-operated cylinder (depending on configuration). The simplicity of the mechanical action paired with quality materials means the lock delivers consistent performance over thousands of cycles, with minimal maintenance required. The DT6301 features a 60mm backset, a common and versatile measurement that defines the distance from the edge of the door to the centerline of the lock’s cylinder or latch mechanism. This backset size is widely compatible with most standard door preparations, making the rim lock suitable for both new installations and retrofit upgrades in existing doors where a dependable surface-mounted locking solution is needed. This rim lock is designed to be mounted on the interior face of the door, with the lock body and latch visible from the inside but secured to the door panel to provide a strong mechanical locking action. Rim locks are especially useful when additional locking capability is desired in conjunction with a primary latch set, or in applications where mortise lock preparation isn’t feasible or preferred.
