Transom knot

This adaptation of the constrictor knot (see page 153) is a neat and minimal way to seize long,

thin items at right-angles to one another—for instance, garden trelliswork or lightweight loads
(such as canoe paddles) to a car’s luggage rack.

Take a short piece of cord and pass the working end in a figure-eight around the two items (1),
crossing on top, to enclose both pieces to be seized (2). Lead the end over its own standing part to

tuck under-under (3). Tighten the knot by pulling on both ends at once (4).
