MailCase in Stainless Steel

The stainless steel MailCase offers unmatched protection against rust in corrosive environments. This includes coastal environments as well as harsh winter climates where roads are salted.

The brushed finish on the stainless MailCass carries an exclusive, stunning look in front of your home or business.

You may have noticed that the MailCase is also available in powder coated zinc-alloy steel.  Sometimes customers ask us what the difference is between stainless steel and zinc alloy steel.

The main differences between our zinc alloy mailboxes and our stainless steel mailboxes are the composition of the metal, and the fact that our zinc-alloy mailboxes are powder coated and our stainless steel mailboxes are unpainted with a brushed finish.  Otherwise the mailboxes are identical. They are the same size, use the same gauge steel, have the same features and have the same level of security.

Zinc alloy steel has zinc and aluminum added to the steel.  MailCase mailboxes made with zinc alloy steel are powder coated and are available in different colors.

Stainless steel does not contain zinc, but instead contains chromium and nickel.  This gives stainless steel unique properties:

  • Stainless steel can be used in highly corrosive environments (where there is lots of salt in the air or on the roads).
  • It does not need to be painted.  Unpainted stainless has an exclusive, stylish look.  
  • It has high hardness and strength.  This makes it strong but difficult to fabricate.
  • It is non magnetic.

While our powder coated zinc-alloy steel mailboxes have excellent rust resistance, some people live in places where there are high levels of corrosion.  This includes places where there is a lot of salt in the air (i.e. close to the ocean) or places where there is a lot of salt on the roads (busy streets in winter climates).  These customers will need an even higher level of rust protection than zinc-alloy steel. These customers will need stainless steel.

Stainless steel is more expensive for several reasons.  First, chromium and nickel are expensive metals, and stainless steel contains a lot of both metals.  Second, since stainless has high hardness, it is difficult to fabricate.  Our factory requires a 45 ton press to stamp stainless steel parts. Finally, the surface of the mailbox has a brushed finish.  It is labor intensive to put the brushed finish on the MailCase, but the result has a stunning look.

There are typically 2 types of customers who buy a stainless steel MailCase:

  1. Customers who live in a highly corrosive environment.
  2. Customers who want the exclusive look of brushed stainless steel.

We recommend cleaning your stainless steel MailCase ever year or two with a product called Barkeepers Friend, which can be found in most supermarkets in the household cleaning aisle.  Even though stainless steel will not corrode, in some climates stainless steel can have surface discoloration.  Barkeepers Friend will remove any surface discoloration and keep your stainless MailCase looking great for years.

High Security Pry Shield

Stainless Mailbox Pry shield
Pry shield logo

The primary way criminals attack locking mailboxes is through a pry attack on the lower door.

To protect against pry attacks MailCase uses the Pry Shield, which is a ledge covering the top edge of the bottom door. When most criminals see the Pry Shield they leave your mailbox alone and move on to an easier target.

Four Point Pry Protection

On the inside of the MailCase we’ve engineered our patent pending Four Point Pry Protection system with our exclusive Hammerhead Latch.

Latch Retention Bracket and Hammerhead Latch

First, we weld a steel bracket to the lower door to protect the latch.  Next, our Hammerhead latch is made from tough stainless steel with a strong hook on the end.

Reinforced Center Frame and Binder Bracket

The center frame of the MailCase is made from heavy, 12 gauge steel and is formed in the shape of a C beam that won’t deform even during extreme pry attacks.

Hammerhead Binding Action

During an extreme pry attack the hook engages this Binder Bracket that is welded to the C-Beam, which binds the door closed. The stronger the pry attack, the stronger the hook holds the door closed.

Lower Brace

We’ve added extra bracing to reinforce the lower door.

Superior Construction

The MailCase has a delivery tray welded to the inside of the top door. The shape of the delivery tray makes it difficult for criminals to reach inside the mailbox.

Additionally the MailCase is 20” tall. This height, combined with the shape and configuration of the delivery tray makes fishing attacks on the MailCase extremely difficult.

High security tubular lock
Tubular Lock
High security tubular lock

MailCase uses a tubular lock. This is is the same lock used on vending machines. Tubular locks protect against picking and drilling of the lock.

All MailCase mailboxes are keyed differently.

The MailCase comes with six keys. We don’t make the locks and keys ourselves, we get them made by our lock supplier who specializes in tubular locks.

We don’t keep copies of your keys in our shop. Since we don’t make the locks and keys ourselves we are unable to provide you with more than 6 keys.

If you need more than 6 keys most good locksmiths have a round key duplicating machine and can make duplicates for you.

The doors on the MailCase are attached using solid rivets that are reinforced by welds. Most other mailboxes use hollow rivets which pop off easily during a pry attack.

The delivery tray, top, side, and rear panels of the MailCase are made using 14 gauge steel. The two front doors and the bottom panel are made using 12 gauge steel.

MailCase Patented Dual Delivery System

Mailcase’s patented dual delivery system makes receiving packages and regular mail a breeze.  Your mail carrier will put packages in the mailbox using the delivery tray. The rest of your mail your carrier will put through the narrow slot. This makes life easier for your mail carrier since they can put everyday mail through the narrow slot using one hand while seated in their mail truck.

Package Delivery

The MailCase takes packages using the delivery tray.

The size of package that can fit depends on if it is a soft package or a rigid package. If it is a soft package then the MailCase can take a fairly large soft package, or multiple soft packages at the same time.

If it is a rigid package then the size that can fit depends on the thickness of the package. If the package is too thick then it will not fit. The following are examples of package sizes that can fit.

The easiest way to describe it is to say that something the size of a large phone book would fit, but something the size of a shoe box would not fit. For additional information about package delivery visit our FAQ page under the “PRODUCT” heading.

Large capacity mail storage

The large capacity of the MailCase allows it to hold several days of mail.

The MailCase only has a front access door available. One of the main expenses of building a locking mailbox is building and securing the lower access door. By adding a rear access door it would increase the cost of the MailCase. We don’t have very many customers who need a rear access option so to keep the MailCase affordable for everybody we don’t have a rear access door option available.



The MailCase prevents leaking by using rubber gaskets on both the top and bottom doors.


We caulk the interior front and rear corners with 100% silicone.

Outgoing Mail

stainless steel outgoing mail clip

Outgoing mail goes in a metal clip located on the inside of the top door. When your carrier opens your top door to deliver your mail, they will see the outgoing mail in the clip and take it with them.

The outgoing mail clip on the MailCase will hold a handful of letters or invitations. It is big enough to hold a Netflix DVD, but would not fit a 9” X 12 “ flat envelope.

According to USPS regulations, it is not possible to lock outgoing mail on a curbside residential mailbox. For more information about locked outgoing mail visit our FAQ page under the heading “SECURITY.”
