Mezuzah: Difference between revisions

#While Sephardim place the mezuzah straight up<ref>Rashi Menachot 33a s.v. pesula, Shulchan Aruch Y.D. 289:6, Ben Ish Chai Ki Tavo Year 2 Halacha 7. This was also the minhag of the Gr"a (Biurei Hagra 289:14 and Maaseh Rav n. 97). Also see Orchos Rabbeinu 1:page 378:27 who quotes that the Chazon Ish and Steipler put their mezuzot on a small slant because if it would be on a diagnol one doesn't fulfill the opinion of Rashi or Tosfot. </ref>, Ashkenazim place it on a slant, with the top leaning towards the inside and the bottom towards the outside.<ref>Rabbenu Tam cited by Tosfot Menachot 33a s.v. ha, Rama 289:6, Levush 289:6, Chayei Adam 15:19, Minchas Elazar 1:36:1, Pitchei Mezuzahs 289:57, Chovat Hadar 9:footnote 20. Chovat Hadar 9:footnote 20 explains that the reason for this is that the opinion of Rashi says if you place it sideways it is not kosher, while Rabbenu Tam Menachot 33a s.v. ha holds that if it is straight up it is not kosher, so Ashkenazim try to fulfill the mitzvah according to both opinions. Rav Wosner (Kovetz Mbet Levi v. 2 p. 131) holds that it isn't put up on a 45 degree angle, rather it is put on a small slant. Orchot Rabbenu v. 3 p. 173 writes that the Chazon Ish put his mezuzah on a slight slant, with the top of the mezuzah 3 cm from the bottom of the mezuzah (approximately at a 75 degree angle).</ref>
