What to Look for When Buying Locking Mailbox

Finding the best locking mailboxes can be a little complicated. After all, several components impact which one best fits a person’s preferences. So, let’s do a quick overview of these factors, which will help ensure you pick a perfect new locking mailbox.

Security Features and Locks

The entire purpose behind security mailbox locks is to secure your mail from would-be thieves. So, it makes sense that the first essential component is each model’s security level. Buyers would be wise to stick with mailboxes with either a cam lock or wafer tumbler locking system.

As any locksmith would tell you, these locking mechanisms are hard to pick. I’d also recommend looking at options with robust latches and baffle doors. These aspects will stop people from prying open your mailbox.

It’s essential to consider the mailbox slot’s size, as well. You don’t want a slot with enough space where someone with small hands could easily reach your mail. It defeats the entire purpose of getting a new locking mailbox.

Construction Quality

Each mailbox will have a specific construction material used to build it. As you can imagine, it’s essential to ensure this material offers durability and stability. It should have no problems withstanding constant sunlight, rain, or rusting issues.

In most cases, galvanized steel ends up being a very desirable material, so it shouldn’t have any issues meeting all of these requirements. But I’d suggest making sure its thickness is at least 12 gauge or more.

Another thing to consider is the mailbox’s finish. You’d be much better off with a powder finish rather than simple paint. This attribute should help the mailbox remain relatively safe from chipping and scratches.

Available Internal Space

You’ll also need to consider the amount of internal space for each mailbox. In other words, buyers will have to think about their regular type of mail. People who only receive bills, notices, and letters would do fine with smaller mailboxes.

But if you often receive big packages, a larger option would be a lot more suitable. Magazines are another large piece of mail that could affect this decision. You might also want to get a larger mailbox if mail is left unattended for weeks without a pickup.

Protection Against Elements

Your locking mailboxes will be outside and require protection against the elements. As a result, buyers will come across some options more capable of withstanding those issues than others. For instance, high-quality locking mailboxes will have a UV ray deflection agent.

It’ll keep the mailbox protected against constant sun exposure issues. Furthermore, some mailboxes will have a non-metal outer construction material to prevent rusting. But the most damaging issue to prepare for would be water damage.

Each mailbox will need to offer waterproof capabilities. Otherwise, your mail will become soaked anytime it rains.

Type

In most cases, locking mailboxes fall into one of three types. These devices are either wall-mounted locking mailboxes, freestanding locking mailboxes, or curbside mailboxes. Wall-mounted options will attach to your garage, house, or gate.

Meanwhile, curbside mailboxes will typically be set up on a post near your curb. But a freestanding locking mailbox will stand by itself without needing any support. It allows users to put it by their porch simply, and it’s ready for usage.

Each buyer will need to decide which type works best for them. Honestly, each type has situations where it would fit better. So it’s essential to put some real thought into which one best suits your particular circumstances.

Does USPS Allow Locking Mailboxes

Postal Service regulations do allow locking mailboxes. However, they must meet the same regulations as a standard mailbox and be approved by the postmaster:

How Does the Mailman Get Into a Locked Mailbox

Your mail carrier doesn’t need access to the key of an individual locking mailbox when they deliver mail. They can drop the mail through its slot, and it’ll be protected against mail thieves. No one should be able to access your mail bundles besides someone with the key.

If you have outgoing mail, I’d recommend dropping it in a nearby postal box. If you don’t, the package or letter will be unprotected while waiting for the mail carrier.

How Can I Make My Mailbox More Secure

There are different locking mailbox measures. One good starting point would be purchasing a high-quality locking mailbox. Another idea is reinforcing the mailbox’s post to resist tampering or other issues. You could also set up cameras around your mailbox to ensure no one steals your stuff.

How Do I Change My Mailbox Lock

In most cases, people will need to hire a locksmith when changing locks on a locking mailbox. But if you have experience changing locks, there’s no reason you can’t do it yourself:

Conclusion

These discussions should’ve provided some helpful insight into what’s the best locking mailbox for your needs. It’s now time to use these resources during your search. From there, the right choice should become apparent rather quickly.
