An improved roller latch bolt that asymmetrically locates the roller within a roller support is presented. The improved design allows for a roller to make contact with a ramp surface of a corresponding strike plate on a sweep side of the plate and allows for the roller support to make contact with the strike plate on a latch side of the plate. The improved roller latch bolt maintains the smooth operation of roller latch bolts while also providing the increased door security and other benefits of non-roller latch bolts.
