  • Publication number: 20190345737
    Abstract: An adjustable latch configured to accommodate different backset lengths. The adjustable latch includes inner and outer housings, at least a portion of the inner housing being structured for axial and rotational displacement within the outer housing as an engagement projection of the inner housing is displaced about an adjustment slot of the outer housing. The apparatus may include a bolt assembly having a bolt rod and a latch bar, the bolt rod having projections that are structured to be adjacent to the latch bar when the bolt rod is at a first rotational position and at first or second axial positions. When the bolt rod is at a second rotational position, the axial positions of the bolt rod and the inner housing relative to at least the latch bar and outer housing, respectively, may be adjusted to adjust the backset setting of the latch.
