ABSTRACT:
An adjustable deadlatch for a lockset for adjusting to either of two backset positions, including a first cylindrical member having a first particular diameter. A second cylindrical member has a second diameter larger than the first diameter and with the first and second cylindrical members located in a telescopic arrangement. A detent is formed between the first and second cylindrical members and has two longitudinal locking detent positions corresponding to the two backset positions. A deadbolt is located within the first cylindrical member and includes a longitudinal opening. A longitudinal portion of an actuating member is located within the longitudinal opening in the deadbolt. The longitudinal portion includes a longitudinal slot having a length corresponding to the distance between the two backset positions. A pin member passes through the deadbolt and has an inner end located in and guided by the slot. A telescopic adjustment of the cylindrical members between the two detent positions provides for an adjustment of the pin in the slot and thereby an adjustment of the deadlatch corresponding to the two backset positions.
