Thank you for selecting Salsbury’s in-ground mounting kit.
This instruction sheet is for installing the in-ground mounting kit into a
concrete footing and installing a classic mailbox post onto the in-ground
mounting kit. Other installation instructions are available for assembling the
post, installing the mailbox, and mounting a newspaper holder. All hardware
to assemble the classic mailbox post to the in-ground mounting kit is
provided with the mounting kit.
When you install a curbside or rural 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.
To install the in-ground mounted kit, begin by digging a hole for the concrete
footing and then prepare the concrete. The top surface of the footing should
be about 15” by 15”. The concrete should extend into the ground 24” or
greater if your local frost line is deeper. Installing the concrete below the
frost line will prevent movement during ground freezing and thawing. The
bottom of the hole for the concrete footing should be filled with a depth of
about 6” of gravel to promote drainage under the post. The top of the footing
should be sloped for water runoff.
When digging the hole for the footing, be careful to not puncture water,
sewer, or gas lines.
After digging the hole, fill the hole with the prepared concrete mix to within
two inches of where the top plate of the in-ground mounting kit will be
positioned. Prod the mix with a stick while filling to reduce any air pockets.
Set the post of the in-ground mounting kit centered into the concrete. Use a
carpenter’s level on the top plate of the in-ground mounting kit to ensure that
it is level. Periodically check the level as the concrete is curing. Fill the top
of the concrete with soil after it has cured.
To install the classic mailbox post to the in-ground mounting kit, install four
(4) 3/8” - 16 x 1.75” long hex bolts through the base of post and through the
four (4) tapped holes on the top plate of the in-ground mounting kit. Cover
the hex nuts with cap plugs. Installation is now complete.

Place the four (4) M10 x 1.50 x 100 mm long hex bolts into the concrete in a
10” x 10” pattern protruding at least 1” above the concrete surface to align
with the holes in the base of the post. The concrete footing should include
