Round lashing

The other name for this seizing is a sheer (or shear) lashing. The name comes from its use by

sailors, construction workers, wilderness pioneers, scouts, and guides to lash up a triangular A-
frame of poles (known as sheer legs) for rigging a block and tackle. A couple of these lashings
will also serve to combine short lengths into longer ones by tying two or more together.

Begin with a clove hitch (see page 150) in the standing end around one pole (1). Then take the

working end eight or nine times, firmly but not too tightly, around both poles (2). Secure the
arrangement with two or three frapping turns taken between the poles, and finish off with a second
clove hitch (3). Repeat the process further down the poles (4). Opening the two legs of an A-frame
(5) will, of course, tighten a single lashing. Any looseness in a pair of lashings on poles that remain
in line with one another can be eliminated only by driving one or more wooden wedges into any

available spaces.
