A frame assembly includes an elongate frame jamb and an elongate hinge reinforcement member, the elongate hinge reinforcement member being secured to the elongate frame jamb such that the elongate frame jamb may be vertically supportable by the elongate hinge reinforcement member at a reinforcement member base end. The elongate hinge reinforcement member is retained within a jamb longitudinal channel formed by the elongate frame jamb. The elongate hinge reinforcement may be configured to include mounting holes located substantially equidistant between side reinforcement walls of the elongate hinge reinforcement member.
