This Kashrus Alert was issued by cRc (Chicago): Until 2017, the cRc recommended certain readily available fencing material (commonly sold in Home Depot) to be used for schach and provided detailed instructions on how to place them on the sukkah.  However, based on feedback from consumers on the sturdiness of those materials and how they were being used, we stopped issuing those recommendations [and also stopped researching these types of products] because we determined that there is a reasonable chance that some people will end up not having kosher schach for their sukkah. We suggest that consumers use traditional schach material such as bamboo poles, tree branches, or mats specifically certified for sukkah use.
