This Abloy key-in-knob cylinder is designed to fit in the Schlage B360 deadbolt, the most common deadbolt found in hardware stores. Note that the Abloy Protec system requires an additional 90 degrees of key rotation in addition to what you are used to. See the videos below for clarification. The Abloy cylinder includes two keys, the code card. This is a combination of Abloy part numbers CY410N and tailpiece 801945.
