If you're trying to figure out if the Architectural Mailboxes 6300B-10 Oasis 360 Locking Parcel Mailbox will fit your space, knowing the dimensions is pretty important.
Now, while the exact dimensions weren't mentioned upfront, we found that this mailbox is designed to fit a wide range of parcel sizes, all while keeping your mail secure with its lock.
The manufacturer mentions that it comes with pre-drilled mounting holes sized at 4 inches by 10 inches, which should work with lots of different mounting plates.
Keep in mind, though, you won't find mounting hardware in the box, so you'll probably need to grab some screws or bolts from a local hardware store.
From our research, a stable and secure installation is essential, so make sure your post or surface can match up with those pre-drilled holes.
Some folks did mention needing to make a few tweaks to get everything lined up just right, so maybe have a drill or extra brackets handy.
Long story short, while the mailbox is great for handling your mail and packages, just be ready to pick up some extra hardware to avoid any surprises when setting it up.
