On Friday afternoon, check our website or call the Eruv Hot-Line at 781-446-9797 to find out if the Eruv is "up" (valid) or "down" (not valid). The eruv may be relied upon only if you determine that its status is "up."
The Nonantum Eruv was constructed and is managed under the auspices of Rabbi Moshe Heinemann of Star-K in Baltimore.
Its operation is supervised by Rabbi Naftali Horowitz (The Bostoner Rebbe) as Rabbi Heinemann's local agent.
Rabbi Joseph Polak, who served as the Consulting Rabbi of The Adams Street Shul at the time we constructed The Nonantum Eruv and placed it into service, provided the following instructions:
The eruv may be relied upon only if you determine that its status is "up." Even though it is almost always up, the default presumption each Shabbat is that the eruv is "down." Until one makes specific inquiry, one must regard the eruv as invalid.
An eruv only eliminates the rabbinic extensions to the Torah prohibition of "bringing". It does not override the laws of muktzeh. (In other words, anything that one can't touch on the Sabbath isn't made touchable by an eruv.) Carrying an umbrella is still prohibited. Carrying items that are intended to be used only after the Sabbath ends (such as car keys) is still prohibited, even within an eruv.
Please support the maintenance of the eruv by making a contribution to The Eruv Fund whenever you can.
