" When 3 or more poles overlap in turn the self-supporting structure formed is called a reciprocal frame"
This simple concept is at the heart
of every ReciproBoo shelter.
With the ReciproBoo shelter it is 4 poles of bamboo or steel that overlap reciprocally and support each other.
It is this ability to span a large space using minimal materials and at the same time support a heavy weight using simple overlapping joints, that makes the concept ideal for shelter construction.
