Trim any projecting wires from each edge of fence using the wire cutters.
Align the two fences so that they are matched evenly, with both the top and bottom being flush.
Slide an aluminum crimp onto each external wire on both fence sections, starting at the top, and crimp it using the crimping tool.
Repeat the procedure, putting one crimp in every section for the entire width of the sections in order to attach them together.
