ACC 301 Rim Cylinder
The ACC 301 Door Lock provides a reliable mechanical security solution for residential and light commercial entry points. This rim cylinder features a durable copper-plated finish that resists atmospheric corrosion while maintaining a professional aesthetic on timber or metal doors. It serves as a direct replacement component for standard night latch assemblies and rim-mounted locking hardware.
Built for the Job
Site supervisors and maintenance contractors frequently specify this hardware for rapid lock barrel replacements. The unit integrates seamlessly with existing surface-mounted deadlocks or night latches, allowing for a security upgrade without replacing the entire internal mechanism. This component is particularly effective for facility managers overseeing multiple units where key control and hardware uniformity are required. The copper plating provides a protective layer against moisture, making it suitable for both interior doors and sheltered exterior applications. Its standard dimensions ensure compatibility with a wide variety of third-party lock bodies found on construction sites and renovation projects.

-
Ensure the tailpiece is trimmed to the correct length using pliers or a hacksaw to match the door thickness.
-
Apply a dry graphite lubricant to the keyway every six months for optimal performance in dusty environments.
-
Align the cylinder mounting screws carefully to avoid cross-threading the backplate during high-speed driver use.
-
Check that the trim ring sits flush against the door face to prevent moisture ingress behind the cylinder body.
