Q. I'm trying to make an eruv for my cottage yard, can I use a light pole for "tzuras hapesach", that it's base is wide and has a marked indentation were the diameter of the pole becomes smaller (by about an inch). This base is well over a meter high (more that ten tefachim). Over that height, the tube begins to taper off and gets smaller until it reaches the lighting fixture, which is well over three meters. My question is, can I just put a cord around the top of the pole, underneath the fixture. This should not be considered “min hatzad” as the base would serve as a "lechi", is that OK?
A. It would seem from your question that the base, being round, protrudes from all sides of the pole. If the string were attached around the top of the pole, even if it is wound up around it, it would then have to cross over that protruding edge of the base, as it continues to the next light pole. The base would then become a lechi that virtually extends directly upwards towards the string, and it would be a proper Tzuras Hapesach.
