Step 1 – Assembly of Vertical Rack Rails
1. Lay two vertical rack rails on the floor with flanges facing each other.
2. Position one extruded base angle and one extruded top angle on the vertical rack rails as shown in the
following figure.
3. Insert six 3/8 x 16 x 1” hex head bolts, 3/8 lock washers, and 3/8 hex nuts. Hand-tighten only.
4. Repeat for second set of vertical rack rails.

Step 2 - Final Assembly of Rack
1. Position both vertical racks, assembled in Step 1, on their sides on the floor approximately 23 inches
(584mm) apart. Extruded base angles should face away from each other.
2. Position the base pan near the extruded base angles and the upper support plate near the extruded top
angles on the vertical rack rails.
3. Attach upper support plate and base pan to assembled vertical rack rails, as shown in figure on next page.
Insert twelve 3/8 x 1” hex head bolts, 3/8 lock washers, and 3/8 hex nuts. Hand tighten only.

4. Raise the frame to an upright position.
5. Using a carpenter’s square, align the vertical rack
rails, extruded top angles and extruded base
angles to square.
6. Tighten all bolts securely.
7. Completed frame may be installed onto floor
attachments forward, center or to the rear using
the extruded base angle.
Installation
Note: Racks are approved for mounting on concrete or other non-combustible surfaces.
1. The equipment rack must be securely anchored to the floor or to an equally stabilized and secure
surface using approved mounting hardware
2. The structural integrity of the rack will only be as good as the quality of the rack to floor attachment.
Using improper sized anchors or failing to secure all floor bolts can result in structural failure and
possibly personnel injury.
3. Racks tend to be top heavy and as such should be anchored as soon as possible to avoid the
possibility of tipping over. Never install equipment until the rack is fully locked down and secured
to the floor.
