Kashrus of Battim

Kashrus of Batim for Tefillin

 

The four compartments that make up the batim (the boxes which house the parchment) of the Tefillin Shel Rosh (which are placed on the head) are molded to form a perfect square. However, according to many poskim, including the alter Rebbe, they must be prudos mamash (totally detached from each other). Some poskim are lenient and rule that tefillin are kosher even if there is a small amount of glue between the compartments—as long as it’s not near the top  and it’s minimal The charitzim (grooves) on the outside of the batim—which indicate where the compartments are separated from each othermay not be charitzim mezuyafim (fake), and have to be in the proper place. To ascertain whether there are any issues with one’s tefillin they can be taken to a batim macher (a professional batim maker) to be examined and any concerns addressed. #348?1
