Wide Mailbox – Right Hand Side Flanged

The Wide Mailbox by Urban Metalwork & Design Studio is a low profile, minimalist Mailbox designed specifically for fixing to either Timber or Steel posts.

The design allows for a fully concealed fixing method giving the Mailbox a “floating” appearance on the post it’s fixed to.

Wide Mailboxes have the option of being Right Hand Side Flanged or Left Hand Side Flanged, for flexibility on fixing in either direction.

The image provided at the top of this page shows a Wide Mailbox as a “Right Hand Side Flanged” version.

Wide Mailbox Kit

Urban Metalwork offer a Mailbox Kit, which includes the Mailbox, Post of your choice and Corten Numbers if required.

We can supply this with the Mailbox already installed and fixed to the post, along with the numbers fixed to the post, ready for installation.


When fitting the Mailbox to a Timber Post, your fixings will go from the inside of your Mailbox (the side which butts up against the post) and through into the side of the post.

You can pre-drill holes in the side of the Mailbox first if required.

Note the size of your post before pre-drilling holes to ensure the screw locations will be in line with your post.

The rear door of the Mailbox is large enough to fit a Cordless Drill inside for inserting the screws.

For further information, please contact us via Email.


The Wide Mailbox is fabricated from 3mm thick Corten Weathering Steel.

Mailboxes are supplied in Mill Finish, as new, with little to no weathering typically.

Weathering will take place as soon as they are installed, outdoors & exposed to the weather.

The finished weight of the product is approximately 12kgs.
