Why install a Gibraltar mailbox?
Gibraltar mailboxes are known for their high quality and durability. They are made of heavy-duty metal and are designed to withstand the elements. If you live in an area where snow and ice are a concern, you may want to consider installing a mailbox that is specifically designed for this type of weather.
There are many reasons why you might want to install a Gibraltar mailbox. Maybe you are moving into a new home and want to choose a mailbox that will look good with your new home’s exterior.
Or, perhaps you have recently had your mailbox damaged by vandals or inclement weather and need to replace it. Whatever your reason, installing a Gibraltar mailbox can be a great way to improve the curb appeal of your home.
How to choose the right Gibraltar mailbox for your home?
When it comes to choosing a mailbox, there are many factors to consider. Here are a few tips to help you choose the right Gibraltar mailbox for your home:
Size: The size of your mailbox should be proportional to the amount of mail you receive on a daily basis. If you have a large family or run a business from home, you’ll need a larger mailbox than someone who lives alone or doesn’t receive much mail.
Location: The location of your mailbox will affect how often you use it and how easy it is to access. If your mailbox is far from your front door, you may not use it as often as someone who has their mailbox right by the door. Conversely, if your mailbox is too close to the street, it may be more difficult to access and could put your mail at risk of being stolen.
Security: If you’re concerned about mail theft, look for a mailbox with a built-in lock. This will deter thieves and give you peace of mind knowing that your mail is safe.
Style: There are many different styles of mailboxes available, so take some time to browse and find one that fits your personality and the style of your home.
Installing Gibraltar mailbox in 5 Easy Steps
Gibraltar mailboxes are known for their quality and durability and are a popular choice for both residential and commercial use. Here are four easy steps to install your Gibraltar mailbox:
1. Mark the location
The first step is to position the mailbox post in the desired location. You’ll want to make sure that the post is level, so use a measuring tape and level to make sure it is positioned correctly. Once you have the post in the desired location, use a drill to mark the holes for the anchor bolts.
Mark the location of the intended mailbox on the ground with chalk or spray paint. The post for the mailbox should be installed in a concrete base that is at least 2 feet deep and 2 feet wide.
2. Dig a Post Hole
The first step to installing a Gibraltar mailbox is to dig a post hole. You will need a post-hole digger, which can be rented from most hardware stores. The depth of the post hole should be at least 30 inches.
Once the post hole has been dug, you will need to insert a wooden post into it. The post should be at least 4 feet tall. Dig a hole for the concrete base using a shovel or power auger. The hole should be 2 feet deep and 2 feet wide.
3. Pour Concrete
Now that the hole is dug and the post is set, it’s time to pour the concrete. The amount of concrete you’ll need will depend on the size of your home, but as a general rule of thumb, you’ll want to use about one bag per foot of depth.
Once you’ve mixed the concrete according to the manufacturer’s instructions, simply pour it into the hole around the post, being careful not to get any on the post itself. Use a trowel to smooth it out, then let it cure for 24 hours before moving on to the next step.
4. Attach Mailbox
Place the Gibraltar mailbox post in the center of the concrete base, making sure that it is level and plumb. Use a level to check that the post is straight, then allow the concrete to cure for at least 24 hours before attaching the mailbox to the post.”
Using the screws provided, attach the mailbox to the post. It is important that the mailbox is attached securely so that it does not become loose over time and cause potential damage to your mail.
5. Add Finishing Touch
Congratulations! You have now installed your Gibraltar mailbox. To complete the installation, follow the steps below:
- Add a flag to your mailbox to indicate that mail is being delivered.
- Place an approvals decal on your mailbox to show that it meets postal regulations.
- If desired, add house numbers to the mailbox for easier identification.
