Customer Reviews for VEVOR Through The Wall Drop Box, Heavy Duty Steel Through the Wall Mailbox with 2.8-7.9" 13" Combination Lock, 12.5x6.3x16.9" Mail Drop Box, Dark Gray
It would have been useful to know that the covered slot is not able to be used in an existing door slot. The box works as advertised and expected but I wanted to use the front piece to replace an existing old door slot for mail
It'll work for dropping keys or mail. However if your looking to have the box secure its not. The quality of the lock is similar to a child's diary lock
