Use: The Diagonal Lashing Knot (ABOK # 2115, p 343.) is used to lash two spars together. Unlike the Square lashing which works for right angle crossings, the diagonal lashing secures poles crossing each other at a variety of angles. The choice of a timber hitch is important. Sometimes there is a gap between the poles.
What are the difference between square lashing and shears lashing?
Unlike square lashings, the shear lashing requires eight or ten wraps around the spars before making the frapping turns between the spars to pull the wraps tight (see figure 120). This lashing then ends with a clove hitch on the other spar (see figure 121).
What are the purposes uses of the square lashing?
A square lashing is the most widely used lashing for securing one spar to another when they cross at an angle. It is particularly used to stop spars sliding over each other. A diagonal lashing is used to pull two spars together and prevent them from springing apart, for example, at the cross-brace of a framework.
