The name hardware cloth is a bit of a misnomer, since it is actually made of metal. The cloth comes in a roll and is made of thin-gauge wire that is welded together to form a mesh with tiny square openings throughout. It is used for a variety of purposes, including constructing animal cages and closing up openings in buildings, among others. Attaching the hardware cloth to the installation surface requires only basic tools.
Measure the location where you are installing the hardware cloth with a tape measure to determine the proper length and width. Unroll the hardware cloth on the ground and use a black marker to draw the dimensions on it.
Cut the hardware cloth using a pair of tin snips and following the marker lines.
Hold the hardware cloth in the installation location and place a U-shaped hardware tack at the top edge so that it straddles one of the vertical wires. Tap the tack with a hammer until it is flush with the installation surface. Repeat the process to insert tacks every 4 to 5 inches along the top of the hardware cloth.
Continue installing tacks along all edges of the hardware cloth to secure it to the surface.
