It is recommended that the enclosure be tied to studs due to its

significant total weight including the 3700 series mailbox unit. If

attaching to studs, mark the wall with two (2) vertical lines
representing two (2) wall studs to which the enclosure will be

fastened.

If not attaching to studs, install appropriately strong anchors and

fasteners to engage the outermost slots in the rows of slots in the
rear panel.

Installation instructions are provided as general guidelines. It is advised that a professional installer be consulted. Salsbury Industries assumes no product assembly or installation liability.

Installing Wall Fasteners

Install Type A wood screws, Fig. 3 (or anchors and fasteners) into all
of the outermost slots (or slots engaging wood studs) in the rear

panel. Install two (2) of the Type A wood screws, not provided, (or

anchors and fasteners, not provided) in the rear flange of the top

panel and in the rear flange of the bottom panel so that the four (4)
screws go through the elongated slots in the rear flanges and into the

wood studs. See the “Screw Locations”, Fig. 4.

Screw Locations

Fig. 4 identifies the locations of the Type A fasteners that are used to
attach the enclosure to the wall studs.

Installing Mailbox Unit

Lifting and installing the mailbox unit into the enclosure is a two (2)
person operation. Open appropriate compartment doors to provide

handholds. Lift the mailbox unit and carefully slide it into the

enclosure until the front peripheral flange is flush against the front

flanges of the enclosure. See Fig. 5.

Fastening Mailbox Unit to Enclosure

Open the master door(s) of the mailbox unit until the hold-open rods

at the top inside corners of the doors engage. Install Type B self-

tapping machine screws (provided) in the flanges all around the four

(4) sides of the mailbox unit just behind the master door(s). See the
following illustrations to locate the flanges. Pilot holes are provided

for the screws in the flanges. The double column mailbox unit shown

uses four (4) screws each along the top and bottom flanges. The

single column mailbox unit (not shown) uses only two (2) screws
each along the top and bottom. See Fig. 6.
