The 5 Best Replacement Mail Flags Reviewed

mail-flags-reviewed

Replacement mailbox flags are designed to replace a damaged or worn down mailbox flag.

It's a good idea to replace them- some mail carriers won't know to pick up mail if you haven't erected your mailbox flag.

Plus, if your house is faraway from the mailbox, you'll want the mailman to raise the flag to let you know mail has been delivered, rather than having to walk down the driveway and check it yourself. A real lifesaver if you or a loved one is dealing with a disability.

When it comes to buying a replacement mailbox flag, you'll want it to be:

  • a noticeable color,
  • easy to install,
  • weather resistant.

One of our favorites is the Universal Mailbox Flag- it is designed to work with brick, wood, stone, stucco, metal or plastic mailboxes. It ships with different screws for different installations, and when you push it up it will click" in place. This lets you know that the flag is properly set.

One installation tip: before you drill or screw it in to its final position, make sure you test out the flag's up and down position. Most users told us that installation wasn't too hard, though a few buyers had to put in some elbow grease (and drilling) for more complex installs. 

  • Designed to attach to plastic, wood, stone, metal or stucco mailboxes.
  • This mailbox flag kit ships with fasteners for masonry installation, wood & metal/plastic mailbox attachment.
  • Designed to be resistant to cold and hot weather climates.
  • Engineered to resist fading from prolonged sunlight exposure.
  • Requires 5/32" masonry rated bit, 3/16 metal rated bit or 5/32" rated wood bit.
  • "Finger Grab" protects fingers while raising & lowering the flag.

Let's take a look at 5 of the best-selling replacement mailbox flags on the market today.
