How to Attach Mailbox Flag to Mailbox with 3M Adhesive

1. Clean the Surface:
   Ensure the back of the plastic mailbox flag is clean and dry. Remove any dirt, dust, or debris that may affect adhesion.
2. Peel One Side:
   Peel off the protective backing from one side of the double-sided 3M adhesive tape, exposing the sticky surface.
3. Apply to the Mailbox Flag:
   Carefully place the exposed adhesive side onto the back of the plastic mailbox flag. Press down firmly across the entire surface area to ensure good contact. Let it sit undisturbed for at least 60 minutes at room temperature.
4. Peel the Other Side:
   Once the first side is securely attached, peel off the protective backing from the other side of the adhesive tape.
5. Position and Press:
   Align the flag with the desired location on your mailbox. Press down firmly to adhere the tape to the mailbox surface.
6. Firmly Hold and Bond:
   Hold the mailbox flag in place for a few moments to allow the adhesive to bond effectively. Press the mailbox flag firmly against the surface of the mailbox to ensure a secure attachment. Apply additional pressure if needed.
7. Secure for Optimal Bonding:
   For optimal bonding, avoid disturbing or moving the mailbox flag for at least 24 hours. This allows the adhesive to set and create a strong connection.
Your plastic mailbox flag should now be securely attached using the double-sided 3M adhesive tape. Ensure the adhesive has fully bonded before operating the mailbox flag to prevent any detachment.
 

How to Mount a Mailbox Flag with 2 Bolts and a 3/16-inch Drill Bit:

Following these steps will guide you through securely mounting a mailbox flag using two bolts and a 3/16-inch drill bit. Remember not to over-tighten the bolts during the installation process.
1. Select Mounting Location:
Choose a suitable location on your mailbox to mount the flag. Ensure it complies with local regulations and does not interfere with the mailbox door's operation.
2. Mark Drill Points:
Using a pencil or marker, mark the two points on the mailbox where you'll drill holes for the bolts. Ensure the marks are level and symmetrically spaced.
3. Drill Holes:
With a 3/16-inch drill bit (not supplied), carefully drill holes at the marked points. Exercise caution to prevent damage to the mailbox surface.
4. Prepare the Flag:
If the mailbox flag has pre-drilled holes, align them with the holes in the mailbox. If not, use the drilled holes as a guide for marking on the flag.
5. Attach the Flag:
Place the mailbox flag over the drilled holes, aligning it with the markings. Insert the bolts through the holes in the flag and tighten them securely into the drilled holes in the mailbox.
6. Check Alignment:
Ensure the flag is securely attached and level. Adjust the bolts if necessary to achieve proper alignment.
7. Tighten Securely (Do not over-tighten):
Using a wrench or suitable tool, tighten the nuts on the bolts securely. Be cautious not to over-tighten, as this can damage the mailbox or strip the threads.
8. Operate the Mailbox Door:
Test the mailbox door's operation to ensure the flag does not interfere. Make adjustments if needed.

Give the mounted flag a final inspection to ensure it is securely attached and functions properly
