A casing assembly for a wall opening, the casing assembly comprising:

• (a) a plurality of casing members to be interconnected to form a framed casing having between two and four corners upon assembly, each casing member being channel shaped with a casing surface wall connected to two opposed casing side walls, wherein each casing member has two opposed open ends, and wherein at least one open end of each casing member is mitred at an angle of about 45 degrees such that upon assembly when two casing members are abutted together at a corner they are disposed at about 90 relative to each other;
• (b) at least one corner connector comprising two male connectors generally disposed at about a 90 degree angle to one another, wherein each male connector is configured to engage with and plug into one of the open ends of the casing members;
• and
• (c) attachment means fixedly attaching at least one male connector in one of the open ends of one of the casing members before the casing members are assembled together so that when the casing members are assembled they do not disengage from each other.

A unitized casing assembly for a wall opening, the casing assembly comprising:

• (a) frame members to be interconnected in a wall opening, the wall opening having at least three longitudinal edges, each frame member comprising a jamb surface wall, the jamb surface wall having two opposing lateral edges, each lateral edge being interconnected to a frame side wall at about a 90 degree angle, each frame side wall being configured to lie flat along a wall surface adjoining a wall opening, each frame side wall having clip holders integral with the frame side wall and spaced apart a predetermined distance from the lateral edge of the jamb surface wall;
• (b) a series of casing clips to be fitted and rigidly secured to the clip holders;
• (c) casing members to be attached to a frame side wall by the casing clips, each casing member being channel shaped with a casing surface wall connected to two opposed casing side walls, each casing member has two opposed open ends, and wherein a casing member is disposed substantially in-parallel to a proximal wall opening edge;
• (d) at least one corner connector comprising two male connectors generally disposed at about a 90 degree angle to one another, wherein each male connector is configured to engage with and plug into an open end of a casing member;
• (e) attachment means fixedly attaching at least one male connector in one of the open ends of one of the casing members before the casing members are assembled together so that when the casing members are assembled they do not disengage from each other;
• and
• (f) wherein after assembly the attachment of corner connectors to casing members by the attachment means maintains the position of the casing members along an axis parallel to the longitudinal wall opening edge and the casing clips maintain the position of the casing members in an axis perpendicular to the longitudinal wall opening edge, and wherein the combination of the attachment means and the casing clips provides a unitized casing assembly that is substantially free from disengaging at the corners and is held in the casing assembly is rigid disposed relative to the wall opening.
