Frequently Asked Questions
Will MAILNUT™ work if my door is hanging off or has a broken hinge?
MAILNUT™ works best and is recommended when your mailbox door has full closure and the door and hinges are in place. Mailbox should be mounted properly to the post.
Will MAILNUT™ work if the inside of my mailbox is rusty and/or has peeling paint?
For best results, mount the 3M dual lockpad to a clean, dry surface. MAILNUT™ packaging includes: directions, a sterile alcohol prep pad, a 2" x 2" sand paper square, and a wooden scrape stick to assist in preparing the mounting surface.
How can I be certain MAILNUT™ will work on my mailbox?
There are hundreds of different mailbox models that have been created over the years and to test MAILNUT™ on every mailbox model that has ever been sold would be virtually impossible. So as a general rule if your mailbox door closes over the outside of the mailbox MAILNUT™ is most likely to work. However, if your mailbox door closes into the inside of your mailbox MAILNUT™ would most likely NOT work.
