How to Choose the Right Lockable Mailbox
You have already revealed all the top-notch security mailboxes out there in the market.
But to pick the right one that will best meet your needs, you have to consider some factors before buying.
Our buying guide may help you in this regard.
SECURITY FEATURES AND LOCKS
The most important point of going for a lockable unit is the security of your mail and valuables. So, the first factor you should take into consideration is the security feature of the model.
We recommend you to go for a unit that either comes with a cam lock or wafer tumbler locking system. The reason is both of these types of lock are relatively hard to pick.
Other features that you should consider is the baffle doors and strong latches. Baffle door is by far the best choice to prevent anyone from reaching in to grab your items. Also, check that the insertion slot isn’t very large or easily accessible for small hands to reach your mail through it.
MAILBOX SIZE AND INTERNAL SPACE AVAILABLE
This product is available in different sizes with different capacities. What size mailbox you should pick it all depends on your needs.
Make sure you get the right-sized box for your mailing needs. Also, think about your average mail type and size. Check that it can conveniently accommodate all of your deliveries with ease.
If you travel a lot and your mail gets accumulated for a period of weeks at a time, a large capacity unit will be perfect for you. Again, larger mailboxes are recommended if you frequently receive mails, medicine delivered, big parcels, and larger packages.
But if you are among those who receive only a couple of mails in a week or month, you need to consider a model with a small capacity.
If your regular mail is simply bills, prescriptions, letters, or notices, a small to the medium-sized unit will work well for you.
CONSTRUCTION MATERIALS
This product should be strong, durable, and secure enough to repel any theft attempt. In general, the housing is made of stainless steel, galvanized steel, or aluminum. 14 and 16 gauge galvanized steel is a very desirable material in this regard.
PROTECTION AGAINST ELEMENTS
Mailbox isn’t something you replace each year. So, it should be well-protected against elements. In general, this product is installed at the exterior of the home and faces damaging elements such as continuous sunlight and rain.
However, go for a unit that features a powder-coated finish. That means the letterbox will remain relatively safe from rust, corrosion, and rain. Some models are also protected with the coating with a UV ray deflecting agent to protect it from sunlight. Units with a non-metal outer layer will prevent rusting.
MOUNTING OPTIONS
Residential mailboxes may offer wall mount, freestanding or curbside type installation.
Wall mount models need to be attached to the wall of your office, gate, or garage.
Curbside mailboxes let you mount it on a post near your curb.
Freestanding type stands alone without being supported by anything.
Think about where you plan to install the unit and choose which is better fit for you.
Finally, don’t forget to check your chosen model is USPS approved so that it works well for your mailman.
LOCKABLE MAILBOX PRICE AND YOUR BUDGET
If budget is a big concern for you, no worry. These products are available in various price ranges.
Curbside units are more expensive than wall-mount models. However, price depends on various aspects such as construction materials, locking mechanism, size and capacity, and more.
We advise you not to compromise with the quality for a minor monetary benefit. If vandalizing or mail-theft is a very serious issue in your area, go for a high-end model with strong security features.
