INSTALLATION GUIDE
75 minutes
Normal Install Time
PARTS INCLUDED:
Cab & T Panels Assembly
Tailgate Panel
TOOLS REQUIRED:
Drill 3/8" Nut Driver
PREPARE THE CARGO BED & MOUNT THE COVER
Attach the clamp bracket to the bulkhead, centered side to side and flush
1
with the top rail, using a drill, 3/8" nut driver bit, and four self-drilling screws.
Installing the clamp bracket is easiest
if you pre-drill it using the screws.
Attach a lock-rod striker bracket to each front
2
corner of the cargo bed with its V bend rearward
using four more self-drilling screws per bracket.
Make sure the bracket's legs are located as high
on the bed wall as possible without them break-
ing the plane of the top of the bed rail.
It's OK for the top of the V bend itself
to break this plane.
If you are also installing a Cross Bin, do so now. Refer to page 2 of the
3
Cross Bin Installation Guide for details.
Place the cab & T panels
4
assembly on the front half of
the bed so its leading edge
lines up with the leading edge
of the bulkhead.

Slide the tailgate panel onto the
5
T panel by mating their hinges.
Close the tailgate panel slowly
while holding the lock handle in
the open position.
To avoid hinge damage, do not close the
panel until hinges are fully mated: Tilt the
panel past 90° and push to the left until the
hinge locking tabs interlock and the hinge
barrels are aligned with the leaves.
Turn the tailgate-panel lock handle back to the closed position so that
6 6
the lock rods pass underneath the bed rails. Close the tailgate.
Center the DiamondBack
7
side to side.
Place two cap clamps as far
8
apart as possible at each of the
three ends of the T panel.
Tighten with a 9/16" socket.
Retighten your clamps after 100 miles.
Check them every time you haul on top.

PRE INSTALLATION NOTE:
If your truck has bed rail caps, you should affix
the included bulkhead prep kit prior to install-
ing the DiamondBack 270. Refer to the Bulk-
head Prep Kit Installation Guide for details.
Mating hinges is
easiest when you
line up the longer,
left hinge pin first.
