Roadside Mailboxes
– 4325
4-Wide Spreader & Pedestal Installation Instructions
U.S.P.S. APPROVED
Thank you for selecting Salsbury’s 4325 roadside mailbox. This instruction sheet is for installing 4325 mailboxes on a 4-wide spreader and a pedestal. A different
instruction sheet is available for installing 4325 mailboxes on a 2-wide or 3-wide spreader and a pedestal. Other installation instructions are available for installing
the mailbox on a pedestal, or on a deluxe mailbox post, installing the mailbox on a newspaper holder, and installing the pedestal 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 a locked mailbox should be 41” to 45” from
the ground or street surface up to the point of mail entry. 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. It is important to note that it is not the responsibility of
mail carriers to open mailboxes that are locked, accept keys for this purpose, or lock mailboxes after delivery of the mail.
Installing Mailboxes on Spreader & Pedestal
4384 4-Wide Spreader
All hardware to attach the spreader to the pedestal is included with the pedestal. To attach the spreader to the pedestal, install four (4) 5/16”-18 X 1” long hex flange
head bolts through the four (4) center square holes of the spreader and through the four (4) tapped holes on the top plate of the pedestal. Cover the hex flange head
bolts with cap plugs.
Next install a support arm by installing four (4) 5/16”-18 x 1-3/4” long carriage bolts through the four (4) square holes shown in the spreader and through the four (4)
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 pedestal. 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 support arm.
All hardware to attach the mailboxes to the spreader is included with the spreader. To attach a mailbox, open the front door or rear 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 the 1” tall square spacer, and through the four
(4) 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 other mailboxes. Installation is now complete. Additional hardware provided is not needed and may be discarded.
