Salsbury Industries 3800 Series Installation Instructions

3800 Surface Mount Enclosures
For 3700 Series 4C Front Loading Horizontal Mailboxes
With its high quality design and construction, Salsbury's 3800 series 4C horizontal mailbox surface mount enclosure will provide years of
maintenance free service. Please read this entire document before beginning installation.
WARNING:
Installation of the 4C enclosure and mailbox unit must be to a surface of sufficient load bearing strength.
Attachment of the enclosure to the surface must be with fasteners that can adequately support the weight of the
enclosure and mailbox unit. Installing to a deficient load bearing mounting surface and/or use of inadequate fasteners
could cause the 4C enclosure and mailbox unit to fall from the surface possibly resulting in serious injury. See below for
further information.
Installation Planning
1. Determine the horizontal location of each of the 3700 series
mailbox units with its 3800 series wall mount enclosure.
2. Consider the combined weights in the table below when
designing the wall or selecting the appropriate fasteners and
anchors to be used.
3. If attaching to studs in a custom built wall, determine the
optimum location of the wall studs to which to fasten the
enclosures. Frame the wall with wood studs. Build a robust
wall.
4. If attaching to studs in an existing wall, determine the stud
locations, and position enclosures to maximize the number of
studs to which the enclosures will be attached.
5. If not attaching to studs, choose an appropriate high strength
anchor, especially if attaching directly to drywall.
attaching to drywall, place the anchor and fastener as close as
possible to the studs to which the drywall is attached.
