ACC 270 Series Cylinder Door Lock, Copper Finish, 3 Keys

ACC 270 Series Door Lock

The ACC 270 Cylinder Lock provides a robust security solution for internal and external timber doors in residential and light commercial builds. This mortise-style hardware features a 270mm backplate designed to provide maximum coverage for standard door preparations. The copper finish offers a traditional aesthetic while providing a protective layer against surface oxidation and wear in high-traffic areas.

Built for the Job

Site supervisors and carpenters select this hardware for projects requiring a standard profile cylinder mechanism. The 270mm plate length is particularly useful for retrofitting, as it covers previous screw holes and marks left by older handle sets. The internal mortise case fits standard cut-outs, allowing for rapid installation across multiple units. It functions reliably on doors ranging from 35mm to 45mm in thickness, making it a versatile choice for standard housing developments.

• Residential bedroom and main entry door installations.

• Commercial office partitions requiring keyed access.

• Retrofitting projects where large backplates are needed.
