Red mailbox flags are made of sturdy metal and can withstand hot and cold climates, resist fading from sunlight, and offer a long lifespan. Easy to assemble and install: These red mailbox flags are not universal; ensure your external mailbox has two flag holes—one larger hole measuring 1.2 cm in diameter and one smaller hole measuring 0.6 cm in diameter—otherwise installation may not be possible. The installation process is simple: thread the replacement red mailbox flagpole through the mailbox and secure it with the included accessories. Gravity design: The mailbox flag rises and stands upright by gravity, ensuring smooth operation. Once raised, the flag is less likely to fall down. This updated design reduces wear on components during use, helping to extend the product's life. Add color and visibility to your mailbox with this replacement flag kit. Wide range of applications: Compatible with most standard mailboxes. The red mailbox flag has a modern appearance and will match any mailbox style, making it ideal for replacing damaged or missing flags.
