The reinforcing assembly is configured to reside within a recess or mortise defined within a body of the door. A body of said door latch mechanism is configured to be received, at least in part, within said reinforcing assembly. The reinforcing assembly includes a body having a back plate and one or more walls thereby defining a latch receiving cavity. At least one fastener is configured to secure the reinforcing assembly to the body of the door. The at least one fastener may be oriented substantially normal to the transverse plane of the door when securing the reinforcing assembly within the body of the door.
