Heavy Duty Rural Mailboxes – 4850

Spreader & Standard Post Installation Instructions

U.S.P.S. APPROVED

Installing Mailboxes on Spreader & Standard Post

Thank you for selecting Salsbury’s 4850 heavy duty rural mailbox.

We are confident that the quality and construction of the mailbox will

prove to be a good investment.

This instruction sheet is for installing 4850 mailboxes on spreaders

and Salsbury standard mailbox posts. Other installation instructions

are available for installing the mailboxes and spreaders on a

“modern” decorative post, mounting a single mailbox on a decorative

or standard post, mounting the 4815 newspaper holder, and

mounting the post in a concrete footing.

When you install a curbside or roadside mailbox, make sure that it is

easily accessible to the mail carrier. By regulation it should be 41” to

45” from the ground or street surface up to the inside floor of the

mailbox. The door should be set back 6” to 8” back from the front

face of the curb or the road edge. However, you should check with

your local postmaster to ensure that the mailbox is installed

according to local regulations.

The spreaders are available in 3 widths, for mounting 2, 3, or 4

mailboxes. All 3 widths can be installed on the standard posts.

The mailboxes are mounted to the spreader using four 5/16” carriage

bolts, 1/2” nylon spacers, washers, and acorn nuts. The carriage

bolts are installed from the inside of the mailbox and the nylon

spacers are placed between the mailboxes and the spreader. The

washers and acorn nuts are installed under the spreader. The

middle mailbox on the 3-wide spreader is jointly mounted to the

spreader and the spreader to the post with the same set of long 5/16”

hex washer bolts and nylon spacers.

The top plate of the standard post has 4 tapped holes. The spreader

is mounted to the post using four 5/16” hex washer head bolts. The

2-wide and 4-wide spreaders are mounted directly to the post using

the short 5/16” carriage bolts, while the 3-wide spreader is mounted

to the post using the longer 5/16” carriage bolts and nylon spacers

inside the middle mailbox, holding both the mailbox and the spreader

to the post. Plastic caps are provided for the bolt heads to be used

with the 2-wide and 4-wide spreaders. The plastic caps are not

necessary for the 3-wide spreader, since the bolts are inside the

middle mailbox.
