Abstract: A cover plate according to certain embodiments is configured for use with a mounting plate and a control system, and has a front side and a rear side opposite the front side. The cover plate includes a support substrate, a cover plate coupler, and an electronic device. The support substrate includes an opening sized and shaped to receive a spindle of a door hardware apparatus associated with the rose assembly. The cover plate coupler is configured to releasably couple with a mounting plate coupler of the mounting plate. The electronic device is mounted to the support substrate, and includes a first electrical connector accessible from the rear side of the cover plate and configured for electrical connection with a second electrical connector of the control system, and an electronic component electrically connected with the first electrical connector.

Abstract: An example door closer includes a casing and a pinion rotatably mounted to the casing. The pinion is operable to rotate through a plurality of movement zones, and the door closer is configured to exert forces on the pinion as the pinion moves through the plurality of movement zones. The door closer further includes a plurality of adjustment mechanisms, each operable to adjust the force exerted on the pinion as the pinion travels through a corresponding movement zone. The casing is provided with indicia that correlate each of the adjustment mechanisms to the corresponding movement zone.

Abstract: An exemplary door closer has an adjustable size and includes a rotatable member operable to adjust the size and an indicator mechanism configured to indicate the current size. The indicator mechanism includes a cover mounted to a housing of the door closer and a dial rotatably mounted to the cover. The dial is engaged with the rotatable member such that the dial rotates in response to rotation of the rotatable member. The cover includes an indicating region, and the dial includes a display surface including indicia relating to the sizes of the door closer. The display surface is non-perpendicular to the rotational axis of the rotatable member. When the door closer has been adjusted to a particular size, indicia relating to the particular size are indicated by the indicating region.

Abstract: An exemplary rose assembly is configured for mounting to a door, and generally includes a cover plate, a mounting plate, and a releasable coupler. The cover plate includes a first opening sized and shaped to receive a spindle of a door hardware apparatus mounted to the door. The mounting plate includes a mounting area, a second opening, and a recessed portion. The mounting area is sized and shaped to receive the cover plate, and the cover plate is mounted to the mounting area. The second opening is sized and shaped to receive the spindle, and is aligned with the first opening. The recessed portion is configured to facilitate removal of the cover plate from the mounting area. The releasable coupler selectively retains the cover plate within the mounting area.

Abstract: An exemplary door closer includes a housing defining a hydraulic chamber having a hydraulic fluid disposed therein. A pinion is rotatably mounted to the housing and extends into the hydraulic chamber. A piston is mounted for reciprocal movement within the housing, and defines a rack engaged with the pinion. The housing further defines an aperture in fluid communication with the hydraulic chamber. A regulating screw is rotatably mounted within the aperture such that rotation of the regulating screw in a first direction advances the regulating screw into the hydraulic chamber and such that rotation of the regulating screw in an opposite second direction withdraws the regulating screw away from the hydraulic chamber. A stop member is mounted in the aperture such that the stop member limits withdrawing movement of the regulating screw to thereby prevent leaking of the hydraulic fluid from the hydraulic chamber via the aperture.
