Square Lashing

( ABOK #2114 )

Animation: Square Lashing

Usage

The Square Lashing is a knot used to bind two poles together, typically at right angles, making it ideal for building structures such as tripods, scaffolding, bridges and towers. It is most often used when constructing load-bearing frameworks, providing stability and strength to the joint. When the poles are tightly bound without gaps, Square Lashing is preferred for vertical or load-bearing connections, while Diagonal Lashing is used if a gap exists between the poles or for bracing. Together, Square and Diagonal Lashings are essential for constructing stable structures.

Structure

Though the Square Lashing has traditionally been started with a Clove Hitch, it can also be started with a Timber Hitch or Constrictor Hitch.

Note

The Square Lashing begins and ends with a Clove Hitch. The initial turns around the poles are called "wraps". The final turns around the center, which tighten the lashing, are called "fraps". The number of wraps and fraps to use can be recalled with the rhyme: "Wrap thrice, frap twice"! Lashing strength is improved if care is taken to lay the rope wraps and fraps in parallel with a minimum of crossing, maintaining maximum contact between the rope and wood.
