Abstract
A progressive deadlatching arrangement for a deadbolt lock prevents an external force applied on the deadbolt from retracting the deadbolt or otherwise compromising a secured door. The progressive deadlatching arrangement prevents external forces from retracting the deadbolt while still allowing an authorized user to operate the deadbolt. ASSA ABLOY Residential Group, Inc. is a subsidiary of ASSA ABLOY AB.
