ABSTRACT:
An adjustable chimney cover is provided which can be adjusted in length and width to accommodate any size chimney. The chimney cover is comprised of a plurality of subassemblies, each of which comprises two side panels and a middle panel. The first ends of the side panels are movably mounted within a guide structure formed in the middle panel to allow the side panels to slide in first and second directions within the guide structure. The overall length of the subassemblies can be adjusted by sliding the panels in the first or second directions. Once the length of the subassemblies has been fixed, the side panels are locked in place. The subassemblies are then placed in an overlapping relationship and adjacent side panels are attached at their second ends. The second ends of the side panels are then attached to a chimney. In order to adjust the width of the chimney cover, additional side panels are used and/or the amount of overlap between the subassemblies is adjusted. Preferably, the second ends of adjacent side panels are attached by weaving a strap through slots formed in the second ends of the side panels and connecting the ends of the strap to a fastener which can adjusted to tighten the strap about the chimney.
