1) Separate backpan from center section and determine hinge side.
THE BACKPAN MUST BE INSTALLED PLUMB AND LEVEL FOR PROPER OPERATION.
NOTE: Ensure the wall to which the backpan will be mounted, consists of two (2) 3/4" plywood
screwed to the studs. All DWR’s may be mounted using the method outlined in step 2, and DWR’s
up to 26” overall depth may also be mounted on concrete walls. You can install 32” overall depth
DWR’s 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 1 1/2" 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.
NOTE: Feet are included with the 24 and 35 rackspace
DWR’s 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.
