7. Affix the Mezuzah

The mezuzah must be permanently attached to the doorpost. Use hammer and nails, glue, or a durable double-sided tape. Position the mezuzah above the one-third mark you've made. It should be towards the outer edge of the doorpost, on a diagonal with the top pointing inwards. (see illustration)

Immediately after reciting the blessing, affix the mezuzah. Do not allow interruptions as you then proceed to the remaining rooms in your home. Remember to affix each mezuzah to the above mentioned specifications.
