Euro & American Lock Cylinders for OEM Door Hardware

Cylinder Profiles, Keying, and Hardware Integration

Lock cylinders convert key rotation into mechanical action—either directly operating latch bolts or interfacing with multipoint lock bodies via tailpieces. Euro cylinders fit standard cam-operated hardware; American cylinders suit mortise locks and single-point deadbolts. Correct cylinder length, cam type, and keyway profile are critical for proper bolt engagement and door operation.

Match Cylinder Type to Lock Body and Door Type

Euro cylinders fit euro-profile hardware on hinged and sliding doors. American cylinders integrate with mortise locks and deadbolts. Identify your existing lock body, measure cylinder length (outside to outside), and verify the cam or tailpiece type. Double-keyed cylinders secure entry and exit on glass doors; active profiles actuate latch systems; inactive profiles are fixed reference points.

Keying, Cylinder Length, and Specification Guidance

Cylinder length ranges 30mm to 90mm depending on door thickness and hardware depth. Measure from the cylinder body face to the tip of the cam or tailpiece. Verify keying compatibility with existing master or core system. G-U tailpieces and Winkhaus one-motion cylinders require precise profile matching to multipoint lock bodies. Incorrect length or cam angle causes binding or failed bolt operation.
