* A jam cleat in which the line is pinched in a v-shaped slot.
* A clam cleat (or jam cleat) in which the rope is held between two fluted stationary pieces. Such a cleat vaguely resembles two halves of a clam shell held back to back. It is more compact than a cam cleat, but the rope is less easily released under load.

to a horn cleatAshley 1993, p. 286. on a dock. The line comes from a boat off the top of the picture, around the right horn, around the left horn, across the cleat from top left to bottom right, around the right horn, and then hitches around the left horn. Note that this line is tied improperly; the line from the boat should initially run to the far (left) side of the horn cleat rather than close (right) side.
Jamming cleat.jpg, A jam cleat. The rope is free to run around the lower part of the cleat (below the screws). The upper part is tapered so that the space between the cleat and the boat gets smaller closer to the screws, causing the rope to jam in the cleat when it is pulled downward.
