Some of the key door handle parts are the following: Door lever or doorknob: This refers to the part that is turned or pulled on to operate the opening mechanism. Latch: This is the internal part that goes inside the door to keep it from swinging open. Latch strike: The latch strike is the slot where the latch enters.

Wall-mounted mailboxes pre-approved by USPS should be installed on the side of the house. 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.

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

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:

1. Residential mail slots are often far more secure than non-locking post mount or wall mount mailboxes.
2. Mail slots are less expensive.
3. 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:

1. Mail slot size
2. Mail slot finish
3. 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:

1. Check with your postmaster
2. Ensure proper mail slot height
3. 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.

To many people, all door handles are more or less the same. Most people are unaware that there are different types and differences between the mechanisms of those types. These differences affect the performance of the handles. That means that each door, depending on its function, will have a suitable door handle to go with it.

Parts of a door handle

Before we get to discussing the types of door handles, knowing the parts that make them up is essential. These parts determine the mechanisms that will allow the handle to operate correctly. They also affect how the overall setup and use of the item. Some of the key door handle parts are the following:

• Door lever or doorknob: This refers to the part that is turned or pulled on to operate the opening mechanism.
• Latch: This is the internal part that goes inside the door to keep it from swinging open.
• Latchstrike: The latch strike is the slot where the latch enters.
• Deadbolt: The deadbolt is a separate locking mechanism usually found above or below the door lever.
• Snib: A snib is a built-in locking mechanism on most door handles. It is the part that the user turns or pushes in order to lock the door.

The way that these parts are made is different. These differences determine the type of the handle.

The types of door handles

There are different types of door handles. They vary based on how they are used and how they look. Choosing a door handle seems like a simple task. While it really is simple, there are some considerations that most people are not aware of. The utility or the aesthetic value of each type of door handle is unique, so you need to choose the correct type. The main types are as follows:

1. Lever latch

Lever latches are some of the simplest door handles available. A simple latch keeps the door shut with this type. A lever handle (thus the name) allows the user to release the latch and open the door. This type usually has an elongated handle, and pushing the handle down operates the latch mechanism inside. Some doorknobs operate based on this mechanism. Turning the doorknob produces the same effect.

This type of door handle is usually found in homes or offices. Due to the mechanism of the lever latch, no lock is usually present. This makes this type of door handle ideal for interiors where locking mechanisms are not necessary. External locks can be installed, however. Deadbolts and chain locks are the commonly installed along with lever latches to provide a bit more privacy.

2. Lever lock

A lever lock door handle is quite similar to a lever latch. The mechanisms and parts involved are almost the same. The main difference is that lever locks have a keyhole for the mortise plate beneath the lever. The door can then be opened freely when unlocked or securely closed when keyed in. It allows for a built-in locking mechanism while keeping the parts and design simple.

Its design makes this type of door handle ideal for interiors. These are best used in places which have rooms that need to be secured, but also need to be accessed freely from time to time.

3. Lever bathroom

Lever bathroom door handles are beneficial. They can be easily locked from the inside, which provides security and privacy. However, that can be unlocked from the outside by using objects that can fit into the knob or handle’s slot. These objects, like coins, can be turned to activate the mechanism of the handle and open the door. This is useful if you have children who could lock themselves in, but then need assistance.

As the name implies, lever bathroom handles are best to use in bathroom doors. That’s because the locks for these doors are able to signify that the room is occupied. Many emergencies can potentially occur inside the bathroom. The simple locking mechanism that needs no key while still providing privacy is advantageous in these situations.

4. Lever privacy

Lever privacy handles are functionally similar to the lever bathroom types. A locking mechanism is built into the handle, and turning the snib on the handle locks the door. It can be unlocked from the outside using a key. No mortise plate is built-in in most cases.

This type of handle is ideal for interiors, especially bedrooms, as it provides both security and privacy while giving only the key holder access from the outside. It is also used as an exterior lock in some cases, although the security it provides may not be enough. That is why deadlocks and other locking mechanisms are added to exterior doors with lever privacy handles.

5. Pull door handles

Pull door handles are ones that do not have any built-in locking or securing mechanisms. No need for latches and latch strikes. They are for doors that are simply designed to open and shut. They come in the following forms:

• Passagehandles: Passage handles are typical in closets or hallways.
• Kitchenhandles: Kitchens often use pull door handles for their doors for ease of access.

Pull door handles are the simplest ones you can find on the market.

6. Electronic locks

Electronic locks are not strictly a door handle type in the traditional sense. These locking mechanisms, however, can be built into doors and can be paired with different handle types. Some electronic locks even have their own unique handles with keypads built into them.
