Whitehall MailVault Modern Square Locking Mailbox – Contemporary Steel Post Mount Mailbox

Upgrade your home or business exterior with the Whitehall MailVault Modern Square Locking Mailbox, a perfect combination of modern aesthetics, durable construction, and reliable mail security. Designed with a sleek square profile, this post-mount mailbox offers both style and performance that stand the test of time.

Crafted from high-quality, rust-resistant steel, the MailVault ensures long-lasting protection against the elements while maintaining a clean, contemporary look. Its top slot (up to approximately 3 in thick) safeguards letters from theft and weather damage; a separate locking compartment stores parcels, though carrier delivery requires giving your mail carrier a key. With easy installation and available options for magnetic 4″ modern numbers and a premium post, it delivers both convenience and curb appeal.

Ideal for homeowners seeking a stylish, secure, and weatherproof mailbox that complements modern architecture.

Key Features:

  • Modern Design: Sleek square shape with clean lines enhances your home’s contemporary look.
  • Durable Steel Construction: Made from high-quality, rust-resistant materials for long-term reliability.
  • Secure Locking System: The locked compartment protects small packages from theft and weather once inside; carrier package delivery requires providing your mail carrier with one of the two included keys.
  • Weather-Resistant Finish: Ensures your mail stays safe and dry in all conditions.
  • Easy Installation: Includes all necessary mounting hardware for quick and simple setup.
  • Optional Accessories: Available with magnetic 4″ modern numbers and a premium post for a complete look.
  • Mail Capacity: Top slot accepts letters and flat mail up to approximately 3 in thick; small parcels can be stored in the separate locked compartment.
  • Access Type: Front-facing top slot for keyless mail delivery, plus a separate locking security door for package storage.
  • Dimension: 19.8" x 11.6" x 11.8"
  • Whitehall mailbox bodies are manufactured in China and other overseas facilities. All components are made in the USA.

Warranty: 1-Year Warranty. The Whitehall Mail Vault is constructed from steel and is covered by a 1-year manufacturer's warranty.
