Stacking PACK RAT® Drawer Units
Rear Mount Bracket Installation (alternate)
If space is critical and/or for some reason you cannot mount the rear in either the preferred method or use the mounting plates
at the rear, you may use the rear mounting bracket. Locate the center line of the housing and place the bracket ush against the
back and ush to the oor. If necessary, you may turn the bracket so the oor ange is under the rear overhang of the housing.
Hole marking will be more difcult. Mark only the two oor holes for drilling. See Blind Fastener Installation Instructions and
cautions before drilling. With Blind Fasteners installed, fasten the bracket to the oor. Mark and drill holes on the back of the
housing for Blind Fastener installation. With Blind Fasteners installed, replace the housing and secure to the bracket.

INSET
Follow additional instructions if mounting to an aluminum truck
bed as explained in the Blind Fastener Installation on page 2.
ALUMINUM TRUCK BED INSTALLATION:
• Do not install bolts in the rear of the upper housing at this time.
• See Inset below for installation details. Do not use outer-most obround holes, fasteners would obstruct lower unit drawer travel.
When stacking PACK RAT® units in an open vehicle, apply sealant (local purchase) to drilled holes in the drawer unit bodies.
With the lower PACK RAT® unit properly bolted in place, mount the rear mounting bracket to the top rear edge of the unit as
shown. The bracket will be mounted to the bottom rst. Put the upper PACK RAT® unit in position on top of the lower and mark
the back mounting holes for blind fastener installation. With the upper housing in proper bolting position (with drawer and rollers
removed), mark through inner two obround holes in the front mounting skid for Blind Fastener installation. With front Blind
Fasteners installed, fasten the upper housing to the lower.
