All known exits to the warren are netted. The bolting rabbit will run into the net, pursing up the net. Care is taken to remove snags that might impede the operation of the net.
The net pegs are made from oak and painted with fluorescent paint. Fred prefers spun nylon cord for the net, the net rings are one piece. Some people have a preference for using hemp cord, but they must not be allowed to be stored while damp, as they will rot.
