ABSTRACT:
A window unit attachment is described in the form of a pivot corner for a single-hung or double-hung window. The pivot corner comprises a unitary pivot pin to allow tilting of the window and optionally a restraining guide to assure proper orientation of the window. The unitary construction of the pivot corner reduces the number of parts needed for tilting or removable single-hung and double-hung window units to a minimum and simplifies construction of these window units.
