Note that mounting fasteners differ according to the building surface being mounted to.
When mounting to wood surfaces, standard 3/8" "lag bolts" are to be used. Generally
however, buildings of concrete and/or brick construction are most common. In these cases
the Mounting Plate must be secured with 4 expanding anchors suitable for this type of
construction. Two types of expanding anchors are included in the kit and must be installed as
follows:
Caution: Note that the correct anchor must be chosen for these types of construction and
must be mounted in 3/8" holes drilled at least 1 1/2" deep.
For solid concrete: ITW Ramset/Red Head "Trubolt Wedge Anchor"
Part No. WW-3822 Tightened @ 25.ft. lbs.
For solid concrete,
hollow concrete block, ITW Ramset/Red Head "Dynabolt" Sleeves,
or brick: Part No. SHN-3817 Tightened @ 15 ft. lbs.
Proper installation of the above fasteners provides more than 1300 lbs. of pull or shear
strength (per fastener).
2. Secure the Base Station Mounting Bracket to the Inside of the Weatherproof Housing
See Figure 16-13. Locate the mounting bracket (supplied with the Base Station) in the position
and drill two 5/32” diameter holes for mounting. Apply a small amount of silicon-seal to the
surfaces. Next, secure the Base Station Mounting Bracket with two 6-32 x 5/8” pan-head
screws, locking hex nut and flatwashers provided.
3. Secure Small Pattern Mounting Plate to the Weatherproof Housing Outer Surface
See Figure 16-14 Position the Small Pattern Mounting Plate on the lower back side of the
weatherproof housing and, using it as a drill guide, drill four 0.375" diameter holes through the
housing. Apply a small amount of silicon rubber seal within and around the holes on the
INSIDE
surface of the housing and then mount the plate in the orientation desired for the
application using the provided 3/8”-16 x 1” hardware (bolt, flatwasher and nut). The blot head
and washer shall be mounted from inside the housing as shown. Use silicon-seal to insure a
weatherproof seal around the bolt head and washer.
4. Provide Signal/Power Cable Access Into the Housing
Depending on the desired orientation of the weatherproof housing, choose a satisfactory
cable-entry point on or near the bottom of the housing and drill a 0.375" hole to accommodate
the provided 1/4" rubber grommet. Use silicon-seal to weatherproof this cable-entry as
needed.
5. Secure the Weatherproof Housing and Mounting Arm to the Plate Mounted on the Building
Surface
The weatherproof housing can now be attached to the building using either length of Mounting
Arm provided in the kit. It may be desirable to run the signal/power cable to the Base Station
inside the Mounting Arm, entering and exiting the cable through the slots provided. Using the
5/16"-18 bolt and locking hex-nut provided, lock the Mounting Arm in place using the locating
holes in the Mounting Plate tubes at each end. (Do not overtighten the hardware as this could
distort the tubes, making future disassembly difficult.)
