ABSTRACT:
A corner lock (20) includes a first leg member (21) operatively connected to a second leg member (22). The leg members generally conform to a portion of the shape of the channel cavities of the sash members (11-14) which they are securing together. The leg members (21 and 22) each have threaded apertures (21g and 22g) formed for receiving fastening members (92 and 93). When the fastening members are tightened in the threaded apertures, the fastening members engage a first corner surface and move the leg members against the second corner surfaces, thereby tightening and securing the sash members together without the necessity of holes being formed in the sash members.
