A residential wall mail slot offers the ultimate in convenience for homeowners lucky enough to still receive walk-up mail delivery.

A door slot must be 1.5 inches wide and 7 inches long or larger. Install the door slot either vertically or horizontally so the bottom of the slot is at least 30 inches from the floor. All door slots must have a flap. Mail slots are convenient for mail carriers, but intruders may also take advantage of them. Burglars are known to slip wires and cords through vulnerable mail slots (or even a hand) to unlock front doors. 1 Other potential breaches can occur with weak front doors and dark corners of your home’s exterior.

When installing a wall mail slot mailbox you can choose either:

Door Mounted – Bursting forth with nostalgia, a door mail slot mailbox can be installed through a front door (or garage door).

Through Wall – Your wall mail slot mailbox can be installed through the wall of your home.

An exterior mail slot cover (or lid) covers the mail slot so that the home remains insulated against the elements. USPS mailbox guidelines require any horizontal mail slot to be hinged at the top and any vertical mail slot to be hinged on the opposite side from the door’s hinges (if mounted on a door).

When the postal carrier walks up to the house, the mail carrier simply lifts the lid on residential mail slots to insert the mail. The mail passes through your door (or wall for wall mounted door slots) and lies securely on the inside of your home, either on the floor or in a mail slot collection box.

Advantages of a Residential Mail Drop Slot

While residential mail slots are only advisable for postal areas with walk up delivery, the advantages of these thru-wall and thru door slot mailboxes are three-fold:

Residential mail slots are often far more secure than non-locking post mount or wall mount mailboxes.
Mail slots are less expensive.
Mail slots do not require the homeowner to exit their home to retrieve their mail.

For disabled persons or elderly persons with mobility challenges, this third advantage of mail slot mailboxes is hands-down the most significant, as their mail can be collected from the security and comfort of their home.

Ordering A Slot Mailbox

When buying residential mail slots, take time to consider these three factors:

Mail slot size
Mail slot finish
Whether or not to accessorize your with an indoor collection box

Mail Slot Size

The size of your installed mail slot should be large enough to accommodate large envelopes, magazine subscriptions, or small parcels, and according to the USPS mail slot requirements, the mail slot size should be at least 1 ½ by 7 inches in size.

Mail Slot Finish

The finish of your mail slot should match or complement the finish of your door or wall hardware. For example, if you have a door entry hardware with a natural patina brass finish, consider selecting a brass mail slot with a natural patina finish or consider a high contrast to that brass finish to avoid finishes that clash.

Mail Slot Accessories

If having your mail scattered across a heavily trafficked floor area is a safety concern, an indoor mail collection box accessory or simple drop basket inside the home is advisable. Additionally, indoor mail collection accessories are also recommended when the floor surface (such as soft wood flooring) can be easily damaged by the regular delivery of parcels or packages that might scratch or ding it.

New Installation Considerations

Investing the time to consider these three factors can also augment the success of installing your mail slot in a new location:

Check with your postmaster
Ensure proper mail slot height
Consider an interior hood installation

Consult with Your Postmaster

First, check with your local postmaster to ensure that your wall mail slot is a viable option for mail delivery to your home. While a trip to any of Europe’s great cities and to many of North America’s large east coast cities quickly validates the popularity of mail slot mailboxes (they are called letter boxes in Europe), mail slots are less common in the vast majority of North America. So, take the time to ensure walk up mail delivery is available to your residence before purchasing a mail slot for your home.

Correct Mail Slot Height

Second, the USPS requires that when installed, the bottom of your residential mail slot must be at least 30” above the floor. While there is no height restriction posted by the USPS, it is advisable that the mail slot be mounted at a height that allows the postal carrier to easily deliver your mail without reaching too high or stooping too low.

Interior Hood Installation

Additionally, to ensure the mail flows smoothly through the mail slot upon delivery, the USPS requires that if an interior hood is utilized for privacy, the hooded portion should not be below the bottom of the outside plate on the horizontal mail slot. For vertical mail slots, the hood should not extend beyond the side of the outside plate on the same side as the door’s hinges. Finally, regardless of orientation, the interior privacy hood should not project more than 2 1/16” beyond the inside of the door.
