Abstract
A magnet support and retainer for post-construction installed interior storm windows formed as a unitary plastic extrusion having a U-shaped pane-receiving portion, a rigid magnet mounting portion and a connecting portion, preferably flexible, formed therebetween. The magnet mounting portion includes an elongate rigid planar strip having a pair of depending edge flanges defining a cavity for tightly receiving a strip magnet of generally rectangular cross-section and an intermediate depending flange including barb portions adapted to be received tightly within a facing groove formed in the magnet. The opposite magnet face is engaged upon a ferromagnetic strip or sash surface for installation of the storm window. Resilience is afforded sufficient to compensate for irregularities in the pane or in the cooperating ferromagnetic surface when the storm window is installed. The magnet is force fitted in the cavity enabling easy assembly.
