3.3 SECURING EQUIPMENT RACKS TO THE FLOOR
Move the racks into the designated positions and prepare to bolt them to the floor. In rare
cases, bolting to the floor may be prohibited. In those cases, bolt the racks to each other
for stability.
Procedure:
1. Using a template, mark bolt locations for each equipment rack to be installed.
2. Drill pilot holes (Drill any required pilot holes to the specified depth of 1-1/2").
3. Drill 1/2" diameter holes for wood and concrete floors.
4. Move racks into position over bolt marks. In general, racks are placed side-by-side in
numerical order, with Rack #1 leftmost when viewed from the front.
5. If necessary, level the racks. The racks should be, at a minimum, approximately
level. If necessary, shim the racks so they are level by eye (use of an actual level is
better).
6. Align the front of the racks.
7. Bolt equipment racks to the floor. Follow the procedure below corresponding to the
type of floor in the shelter. In general, equipment installers will encounter four types
of floor: concrete, concrete covered with linoleum, wood, and raised floors. The
procedure for each type is as follows:
•
For concrete floors , use 1/2" drop-in expanding anchors with an insulating nylon
washer under the fastener head to anchor the racks (see Figure 3-1: Bolt
Assembly Hardware and Figure 3-2: Nylon Washer and Bolt Assembly).
1. Drill pilot holes for the anchors using the appropriate-sized carbide-tipped
drill bit. The pilot holes must not exceed 1-1/2" in depth.
2. Insert the anchors into the pilot holes.
3. Place insulating phenolic strip(s)
2
and under the cabinets/racks before bolting
them in place.
4. Place the cabinet/rack over the holes.
5. Assembly the bolts, fender washers and nylon washers.
6. Insert the bolt and washer assemblies into the pilot holes.
7. Tighten the bolts until firmly set (see Figure 3-3: Concrete Floor Mounting
and Figure 3-4: Bolt Assembly Used to Bolt Rack to Concrete Floor).
CAUTION
Be careful not to over tighten bolts to avoid breaking the phenolic bushings.

Phenolic strips are only required if the floor is pure concrete. Concrete floors covered with linoleum do not require phenolic
strips.
