Best Double Mailbox Posts for Shared Homes and Curbside Setups
The best double mailbox post depends on whether you want a complete metal support or a decorative sleeve that fits over a separate 4×4 post. The Colingmill 43-inch post is suited to buyers seeking a standalone steel option, while Novabright and Ilyapa offer metal designs for two standard mailboxes. Mayne’s double-arm posts are better for buyers who already have a 4×4 post and want a decorative exterior. Compare what each product includes before choosing.
| Product | Best For | Key Consideration |
|---|---|---|
| Colingmill 43-inch Steel Post | Standalone dual-mailbox support | Check installation method and mailbox fit |
| Novabright 66-inch Post | Two side-by-side standard mailboxes | Designed as a sleeve for a 4×4 wood post |
| Ilyapa 43-inch Metal Post | Powder-coated metal construction | Confirm mounting compatibility |
| Mayne Rockport Double Arm | Decorative setup using a 4×4 post | Post, mailboxes, and mounts are not included |
| Colingmill Post With Planter Box | Shared mailbox station with added decoration | Requires ground installation |
Colingmill 43-Inch Galvanized Steel Post
This Colingmill post is best for households that want one steel support for two mailboxes. Its dual-mailbox capacity can serve a multi-family home or keep separate recipients’ mail organized at one curbside location.
The product is made from galvanized steel and includes stainless steel screws. Its mounting plate is described as compatible with most standard mailboxes. Installation options include setting the post in concrete or fixing it to a wooden post, giving buyers flexibility based on the site.
Why it was selected: It combines a stated two-mailbox design with flexible installation options. Limitation: The listing does not specify the exact mailbox mounting-hole pattern, so verify fit before assembly.
Novabright 66-Inch Double Mailbox Post
Choose this Novabright model if you want a tall, side-by-side arrangement for two standard residential mailboxes. Its 66-inch height and double-head design are intended for shared or multi-household setups that need to consolidate mailboxes in one space.
The post is made from galvanized steel, with features described as resisting bending, rust, and corrosion. The listing also identifies it as a weather-resistant metal sleeve for a 4×4 wood post. That makes the wood post an important part of the installation plan.
Why it was selected: It offers a clearly stated dual-mailbox layout and metal construction for outdoor use. Limitation: It is described as a sleeve for a 4×4 wood post, so buyers should not assume the sleeve alone serves as the complete ground support.
Ilyapa 43-Inch Metal Dual-Mailbox Post
The Ilyapa post is best for buyers looking for a black metal design with a universal mounting bracket. It is listed as a 43-by-4-by-4-inch post for two mailboxes, with a powder-coated finish intended for outdoor exposure.
Its construction is described as 18-gauge metal. The manufacturer highlights resistance to weather, impact, chemicals, and fading. The mounting bracket is compatible with Ilyapa mailboxes and a variety of other designs, but the listing does not name every compatible mailbox model.
Why it was selected: The product combines a dual-mailbox format with a stated universal bracket and powder-coated steel. Limitation: Confirm the bracket’s hole layout against both mailboxes, especially if using brands outside Ilyapa.
Mayne Rockport Double Arm Mail Post
This Mayne Rockport model is best for buyers who want a decorative double-arm post and already plan to use a standard 4×4 post. It fits a 3.5-by-3.5-inch 4×4 and supports two mailboxes weighing up to 8 pounds each.
The post is made from UV fade-resistant polyethylene, which is intended to retain color outdoors. Its two paper-holder arms provide the double-mailbox arrangement, while separate components let buyers select their preferred mailbox style.
Why it was selected: It provides a defined two-arm layout and a 4×4-post design. Limitation: The 4×4 post, mailboxes, and mailbox mounts are not included, so this is not a complete ready-to-install setup.
Colingmill Double Post With Planter Box
This 65-inch Colingmill post is best for shared curbside locations where buyers want room for two mailboxes and a planter feature. Its adjustable mounting plates are described as fitting many standard mailbox sizes.
The listing describes an iron frame with a reinforced structure for outdoor use. It is designed to be installed directly into concrete, and the product includes mounting plates and instructions. The compact double-mailbox arrangement can keep separate mail organized at one location.
Why it was selected: It combines dual-mailbox capacity with a planter-box design and stated ground installation. Limitation: Check the available space and mounting-plate fit before purchase; “many standard” does not establish compatibility with every mailbox.
Buying Guide: How To Choose A Double Mailbox Post
Do you need a complete post or a sleeve?
Start by checking what supports the mailbox at ground level. A standalone post and a sleeve for a 4×4 are different products. Novabright is described as a metal sleeve for a wood post, while the Mayne Rockport requires a separate 4×4 post. Factor in those missing components before comparing designs.
Will both mailboxes fit the mounting system?
Compare each mailbox’s bottom mounting pattern with the post’s plate or bracket. “Universal” and “most standard” indicate broad intended fit, not guaranteed compatibility with every model. Check mailbox dimensions and mounting-hole spacing where those details are available.
Which material suits your location?
Galvanized steel and powder-coated metal are options for buyers prioritizing metal construction. Polyethylene offers a decorative alternative in the Mayne Rockport design. Consider exposure to rain, sun, snow, and wind, and follow the product’s installation instructions for stability.
How many mailboxes and how much weight?
Confirm the post is designed for two mailboxes and review any stated weight limit. The Mayne Rockport listing specifies up to 8 pounds per mailbox. The other products described here do not provide a comparable weight limit in the supplied features, so avoid assuming one.
Frequently Asked Questions
Can one post hold two mailboxes?
Yes. The products in this guide are designed or configured to support two mailboxes, but their mounting methods and included components differ.
Does the Mayne Rockport include the 4×4 post?
No. The listing states that the standard 4×4 post, mailboxes, and mailbox mounts are not included.
Is a metal sleeve the same as an in-ground post?
No. A sleeve fits over or works with a separate support post. Check whether a wood post or another support must be purchased separately.
How can I check mailbox compatibility?
Compare the mailbox’s mounting-hole pattern with the product’s bracket or plate details. Contact the manufacturer if the available specifications do not confirm a fit.
Which post is best for a shared household?
Any listed dual-mailbox design may suit a shared household. Choose based on installation type, mailbox fit, material, and whether the package includes the support components you need.
