Heavy-Duty Die-Cast Aluminum Construction
For townhouse mailbox systems exposed to regular outdoor conditions, material choice plays a key role in long-term performance. This replacement mailbox flag is built from solid die-cast aluminum to provide added strength and reliability compared to plastic alternatives.
Plastic mailbox flags commonly fail over time due to cracking, fading, or snapping from repeated use and weather exposure. Die-cast aluminum is less prone to these issues, helping the flag maintain its shape and function through daily operation and seasonal changes.
For reference, the key product specifications are outlined below:
-
Material: Die-cast aluminum
-
Thickness: 1/4 inch
-
Dimensions: 2-3/4 inches wide x 8 inches high x 1/4 inch deep
-

-
Compatible models: Salsbury 3400 and 3500 Series townhouse mailboxes
This construction is well-suited for townhouse mailbox installations where durability, consistent operation, and long-term use are important.
Powder-Coated Red Finish for Outdoor Use
The replacement flag features a red powder-coated finish designed for outdoor visibility and everyday exposure.
Powder coating helps protect the aluminum surface from moisture and sun exposure while maintaining visibility for mail carriers. This type of finish is commonly used on outdoor hardware because it resists chipping, peeling, and fading better than standard painted finishes.

Installation Overview (DIY)

Tools required:
Installation steps:
-
Remove the existing mailbox flag and hardware
-
Align the replacement flag with the existing mounting holes
-
Secure the flag using the included stainless steel hardware
-
Confirm the flag moves freely and remains upright when raised
Installation typically takes about 5 to 10 minutes.

Frequently Asked Questions
Does this fit all townhouse mailboxes?
No. This replacement flag is made for Salsbury 3400 and 3500 Series townhouse mailboxes with a side-mounted flag and a two-hole mounting pattern. It is not a universal fit.
To confirm compatibility:
-
Check the mailbox model number, often found inside the door or on the back panel
-
Make sure the flag mounts on the side panel, not the rear
-
Measure the spacing between mounting holes. It should be about 1.5 inches center to center
If you cannot locate a model number or the spacing does not match, contact our support team with a photo of your existing flag and mounting area. We can help verify compatibility before you place your order.
Does it include hardware?
Yes. This replacement flag includes stainless steel mounting screws and washers needed for installation.
Is it weather-resistant?
Yes. This product is made from die-cast aluminum and features a powder-coated finish. It is made for outdoor use.
Customer feedback collected since 2008 shows that aluminum flags last about eight to ten years in townhouses. Plastic flags in the same setting usually last less than two years.
How do I confirm fit before ordering?
Check your mailbox manufacturer and model number, confirm that your mailbox uses a side-mounted flag, and measure the distance between the existing mounting holes. The holes should be approximately 1.5 inches apart when measured from center to center. If you are unsure, our support team can help review compatibility before purchase.
