1. Separate backpan from center section and determine hinge side.
THE BACKPAN MUST BE INSTALLED PLUMB AND LEVEL FOR PROPER OPERATION.
NOTE: Ensure the backpan is screwed to the studs. All DWRs may be mounted using the method
outlined in step 2, and DWRs up to 26” overall depth may also be mounted on concrete walls. You
can install 32” overall depth DWRs as outlined in step 2 only.
2. Mount backpan to wall (a minimum of 4" clearance
top and bottom is required) using 3/8" dia. lag bolts with
a minimum length of 2" and standard flat washers.
(FIGURE A)
NOTE:
• The standard flat washers must be installed under
the lag bolt heads. Refer to the chart on the previous
page for the number of mounting holes required. All
mounting holes must be used.
• Feet are included with the 24 and 35 rackspace
DWRs only. These feet are to be used when
mounting in close proximity to the floor (4”). The
feet help reduce the shear weight off of the mounting
hardware that is used to hold the rack to the wall
when a significant amount of weight is loaded in the
rack.
