Lockwood C4 570E Cylinder – 50mm & 65mm Long – Cam & Keying Options

Extended Oval Cylinder – 50mm / 65mm Body with Multi-Cam Options

This extended oval cylinder is engineered for doors with increased thickness or offset mortice lock installations where standard cylinders are not sufficient. With extended body lengths of 50mm and 65mm, it provides secure engagement and reliable performance across a wide range of residential and commercial door applications.

Designed to suit multiple cam types (U, V, W, X, Y and Z), this cylinder range offers excellent flexibility for installers and specifiers working with varied Lockwood mortice lock configurations.

Designed for Flexible Installation and Secure Performance

The extended body design makes this cylinder ideal for doors around 50mm thick or where the mortice lock is positioned off-centre. Its non-handed construction allows easy on-site configuration, while compatibility with Lockwood extension kits enables further length adjustment if required.

Supporting Lockwood Generation 6 barrels, this cylinder range is suitable for modern master key systems and structured access control environments.
