Abstract
A plastic back-up shear plate is laterally disposed with a spring fit into the outwardly facing mouth of a metal window frame. The outwardly facing mouth is formed and defined by the window frame. The window frame is an elongated hollow body with opposing outer wall elements which define the outwardly facing mouth. The shear plate is snap fit into the mouth. The shear plate has laterally disposed opposite outer edge portions which are interlockable on the outer wall elements which define the mouth of the window frame. The shear plate has a lateral dimension slightly larger than the lateral mouth dimension which causes the shear plate to snap fit into the mouth with the spring fit. In one embodiment, the shear plate includes support ribs. In another embodiment, the outer base face of the shear plate includes at least one, and preferably two, shim elements which rise above the outer face. The shim elements may be arcuate elements. In another embodiment, compressible shim fingers are utilized. These Finger shims may further include pads.
