Features & Benefits

Secure Through-Wall Installation

Designed for through-the-wall mounting, the mailbox is installed within the wall structure with only the mail slot visible from the exterior. Mail is delivered from outside while retrieval takes place safely indoors, improving convenience, security, and weather protection without occupying interior floor space.

Integrated Rain Channel System

Built-in drainage grooves above and alongside the mail slot help redirect rainwater away from the opening before it can enter the mailbox. This additional layer of weather protection helps keep mail dry during heavy rain and harsh outdoor conditions.

Scratch-Resistant Powder-Coated Finish

Constructed from heavy-duty cold-rolled steel and finished with a durable powder coating, the mailbox resists scratches, chips, and corrosion better than conventional painted surfaces. The finish helps maintain a clean, professional appearance even after years of outdoor use.

Heavy-Duty All-Steel Construction

Heavy-Duty All-Steel Construction

Built entirely from steel, including the mailbox body, access door, and lock housing, this through-wall mailbox offers superior strength compared to standard wall-mounted mailboxes. Designed to withstand daily use, impact, and outdoor exposure, the rigid steel construction helps prevent warping and provides long-lasting protection for your mail and deliveries.

Extra-Large Storage Capacity

Extra-Large Storage Capacity

With a spacious interior measuring 15" x 12.25" x 6.5", this mailbox accommodates far more than standard letters. Easily receive magazines, small electronics, padded envelopes, and multiple package deliveries without requiring daily retrieval. Ideal for homes, offices, and high-volume mail environments.

Adjustable Through-Wall Chute Design

Adjustable Through-Wall Chute Design

The telescoping mail chute adjusts to fit wall thicknesses from 5.5" to 10", making installation compatible with most interior and exterior wall structures. The adjustable design ensures mail drops smoothly into the collection compartment, reducing the risk of items becoming stuck inside the chute.

Stainless Steel Exterior Panel

Stainless Steel Exterior Panel

The exterior mail slot panel is constructed from genuine stainless steel for superior resistance to rain, corrosion, and long-term weather exposure. Unlike painted steel surfaces, stainless steel maintains its appearance without rusting, peeling, or requiring ongoing maintenance.

Viewing Window for Quick Mail Checks

Viewing Window for Quick Mail Checks

A built-in transparent viewing window allows you to see whether mail has arrived without unlocking or opening the mailbox. This convenient feature reduces unnecessary lock usage while making it easy to monitor incoming deliveries at a glance.

Pry-Resistant Anti-Theft Baffle

Pry-Resistant Anti-Theft Baffle

An internal serrated steel security baffle helps prevent unauthorized access through the mail slot. The specially designed anti-reach barrier blocks attempts to retrieve mail or packages from the opening, providing enhanced protection against mail theft.
