A storm protector (20) to be attachable over a window (21) or other opening of a building (22) includes a header (26), a bottom sill (25) and side frames (23, 24) extending between the ends of the header (26) and the sill (25).

A tensioning assembly (32) is positioned in the header (26) and, without disassembling the protector (20), it may be accessed to adjust the tension of the spring (54).
