A ramp element in the strike housing is adjustable relative to the strike and is securable at the time of installation to align the center of the latch bolt and strike. The ramp element has a channel to allow entry and exit of a latch bolt having a dead latch. A keeper engages the dead latch and maintains it in a retracted position when the closure is locked and is released when the electric latch solenoid is energized. ## Claims ### Claim 1 A method for aligning a dead latch with an electric strike disposed in a door frame, the electric strike being operatively associated with a latch assembly disposed in a door, the latch assembly including a latch bolt, the dead latch, and a latch faceplate having a planar surface, the electric strike defining a strike cavity and having a longer longitudinal length than a width, the electric strike including a ramp element proximal to the strike cavity, the ramp element including a ramp surface, a channel defined in the ramp surface, and an axis extending in a direction parallel to the ramp surface and the longitudinal length of the electric strike along the ramp element, the method comprising: identifying a misalignment between the channel and the dead latch, wherein the channel and the dead latch are misaligned when the dead latch is not permitted to pass through the channel as the door is moved from a closed position in a door opening direction; and selectively positioning the ramp element, and thereby the channel, relative to the dead latch so that the channel is aligned with the dead latch when the door is in the closed position to permit the dead latch to pass through the channel as the door is moved from the closed position in the door opening direction, wherein the channel is selectively positioned relative to the dead latch along the axis of the ramp element and in a plane parallel to the planar surface of the latch faceplate when the door is in the closed position. ### Claim 2 (depends on 1) A method in accordance with claim 1, wherein the ramp surface is a first ramp surface, wherein the electric strike further comprises a keeper including a second ramp surface, the keeper having a first position and a second position, the method further comprising: selectively positioning the keeper in the first position to maintain the dead latch in a retracted position; and selectively positioning the keeper in the second position to allow the dead latch to be released from its retracted position. ### Claim 3 (depends on 2) A method in accordance with claim 2, the electric strike further comprising a strike faceplate, wherein the second ramp surface in the second position is disposed at an angle between 30 and 45 degrees relative to the strike faceplate. ### Claim 4 (depends on 2) A method in accordance with claim 2, further comprising: aligning the second ramp surface with the first ramp surface to provide a shingling effect to facilitate smooth passage of the latch bolt from the second ramp surface onto the first ramp surface when the keeper is in the second position. ### Claim 5 (depends on 1) A method in accordance with claim 1, wherein the electric strike includes a housing that defines the strike cavity, wherein the method further comprises: adjustably securing the ramp element to the housing by at least one fastener selected from the group consisting of screws, clamps, jaws, pins, springs, shims and gears. ### Claim 6 (depends on 5) A method in accordance with claim 5, wherein the ramp element defines a slot, and wherein the ramp element is engaged with a sidewall of the housing. ### Claim 7 (depends on 6) A method in accordance with claim 6, wherein the slot and the sidewall have inter-engaging sections. ### Claim 8 (depends on 6) A method in accordance with claim 6, wherein the sidewall includes a shoulder, and wherein the slot engages the shoulder to allow the ramp element to be adjusted along the axis.
