Abstract
A metal frame anchor, such as one used for securing a metal door or window frame to an adjacent wall structure, having a generally rectangular base, two prongs bent upward and then over the base in opposite directions to form clips which open in opposite directions, and the base having at least one set of angularly cut opposite corners. The slidably insertable metal frame anchor is typically disposed in a metal frame element such that the anchor's base is positioned on inside surfaces of the backbends with the two prongs bent upward and then over the base in opposite directions to form clips which open in the opposite directions and which are positioned on outside surfaces of the backbends to which the anchor is clipped.
