The Transom Knot is similar to a Constrictor Knot. It is used to fix together crossed pieces of rigid material and has a wide range of camping and outdoor uses, for example, to fasten tent poles together and kit to luggage racks. If used as a permanent knot, the ends may be trimmed off for neatness.
To Tie a Transom Knot:
Pass the working end behind the upright spar and back across the rope.
Now pass the working end behind the upright spar on the other side of the second spar. Tuck the working end under both turns.
Pull both the working end and the standing part to tighten the knot.
If used as a permanent knot, trim the ends for neatness.
