How is an eruv constructed?

An eruv (technically, an eruv chatzeirot) is a boundary made of natural geographic features (e.g. a cliff), manmade structures (e.g. a wall) or most commonly a series of theoretical doorways which consist of the side posts called “lechis” and the top lintel called “mashkoff”.

There is no requirement for the eruv to be particularly visible, so eruvin are often designed to be as unobtrusive as possible.

In the Northeast, eruvim are typically  established by the attachment of a small string as well as wooden or plastic strips, called “lechis,” to telephone or utility poles.

These are the types currently found in Towns such as Englewood, Teaneck, Tenafly and others in Bergen County.
