Catenary curves are formed when a homogeneous cable is suspended by its endpoints. The word catenary is derived from the Latin word for “chain.” The mathematics of the curves are described by a hyperbolic function. Catenary curves can also be seen in lots of structures from bridge cables, to hanging chains, spider webs – take a look around you!

Tarptent ridgelines are true catenary curves. This design element gives Tarptents exceptional strength, sag resistance, and wind-shedding ability.
