Lashing Knot – Diagonal Details
Found in: Scouting
Also known as: Diagonal Lashing
Use: The Diagonal Lashing Knot (ABOK #2115, p. 343) is used to lash two spars together. Diagonal lashing is different from square lashing. Square lashing is for poles that cross at right angles. Workers use diagonal lashing for poles crossing at different angles.
Tying it: An initial Timber Hitch surrounds both poles. The choice of a timber hitch is important. Sometimes there is a gap between the poles. Pulling on the Timber Hitch closes the gap and allows the lashing to proceed with the poles touching. You cannot use a clove hitch around one pole to pull the poles together, and it might come untied.
Use: The Diagonal Lashing Knot connects two diagonal poles. These poles help brace a rectangular frame. The position of one diagonal in front and one behind creates the gap between the poles often seen in the center.
Options: The animation shows the lashing made on poles that happen to be at right angles. Under such circumstances, a Square Lashing might be as effective. When the angle between the poles is about 45 degrees, diagonal lashing works better.
Frapping Turns: The turns around the Diagonal Lashing Knot pull tight at right angles. People know these turns as Frapping Turns. Pulling them as tight as possible makes the Lashing more secure.
