Installing Mailboxes on Spreader & Standard Post
Thank you for selecting Salsbury’s 4850 heavy duty rural mailbox.
This instruction sheet is for installing 4850 heavy duty rural mailboxes on a 5-wide spreader and a standard mailbox post. A different instruction sheet is available for
installing 4850 heavy duty rural mailboxes on a 2-wide, 3-wide or 4-wide spreader. Other installation instructions are available for installing the mailboxes and
spreaders on a modern decorative mailbox post, mounting a single mailbox on a decorative or standard mailbox post, mounting a 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.
4885 5-Wide Spreader
All hardware to attach the spreader to the standard mailbox post is included with the post. To attach the spreader to the standard mailbox post requires
simultaneously attaching the center mailbox to the spreader and to the standard post. Start by opening the front door of the center mailbox and install four (4) 5/16”-
18 X 2” long pan head bolts through the four (4) square holes in the inside floor of the center mailbox, through four (4) 5/8” nylon spacers (thread onto bolt), through
the four (4) center square holes of the spreader, and through the four (4) tapped holes on the top plate of the standard mailbox post.
All hardware to attach the remaining four mailboxes to the spreader is included with the spreader. Next attach an additional mailbox adjacent to the center mailbox.
Start by opening the front door of the mailbox and install four (4) 5/16”-18 x 1-3/4” long carriage bolts through the four (4) square holes in the inside floor of the
mailbox, through four (4) 5/8” nylon spacers (thread onto bolt), through the corresponding square holes in top of the spreader, and through the corresponding square
holes in the top plate of a support arm (supplied with spreader). Install 5/16” flat washers and 5/16”-18 hex nuts on the ends of the four (4) bolts protruding below the
bottom of the support arm. Complete the installation of the support arm by drilling a 3/16” diameter hole though each hole in the vertical plate of the support arm and
through the post. Install 1/4” flat washers and 1/4” x 1” long lag screws into the post. Cover the lag screws with cap plugs. Repeat these steps for the other mailbox
adjacent to the center mailbox.
To install an outermost mailbox, open the front door of the mailbox and install four (4) 5/16”-18 x 1-3/4” long carriage bolts through the four (4) square holes in the
inside floor of the mailbox, through four (4) 5/8” nylon spacers (thread onto bolt), and through the corresponding square holes in top of the spreader. Install 5/16” flat
washers and 5/16”-18 hex nuts on the ends of the four (4) bolts protruding below the bottom of the spreader. Repeat these steps for the remaining mailbox.
Installation is now complete.
