Back to Back Assembly:

Where two rows of racks are required, two rack assemblies may be 

installed back to back.

Frame Location: 

Locate back to back frames relative to each other as shown in  

Figure 14, such that the rear cross brace attachment holes align 

for the two adjoining frames (The frames will be facing opposite 

directions). All braces must be installed, as described previously, 

except that a single bolt may be used to connect the front and 

rear frames and respective cross braces. The ½-13 x 1.50” long 

bolt supplied with the rack is to be replaced by a ½-13 x 2 ¼” long 

(supplied with racks).
When placed back to back, there must be enough distance between 

the frames to allow all of the braces (four total) to be installed. The 

“X” distance between anchor bolt holes should be as noted in Table 

1 (see Figure 15).

Two step standard racks placed back to back do not need to have 

the frames bolted together. For 2 step EP1 racks a bolt assembly is 

required (C&D part # REO5253 purchased separately). Contact C&D 

for more details.

The EP racks have anchor bolt slots with a 1.06” x 0.69” (26.9 mm x 

17.5 mm) for One Tier and Two Step rack models and a 1.06” x 0.81” 

(26.9 mm x 20.6 mm) for Two Tier and Three Tier rack models.  

The distance between the anchor bolt locations when the racks are 

placed back to back is shown in Table 1 and Figure 15.

Note: There may be a de-rating of anchor bolt load ratings due to the 

proximity of holes. Reference anchor bolt manufacturer’s data for 

information.

NOTE

:

Anchor selection is determined by the anchor type, the diameter of the anchor, the depth of embedment 

and anchor spacing. The selection of the anchor bolt must be reviewed by a structural engineer to ensure 

that the racks will meet the seismic rating for the EP racks.
