protector
Height of tailgate
with protector
Adjust clamps up
or down until they
hold rail level when
tightened
C. Install first clamp as close to front
of bed as possible and use 1/2"
wrench to tighten.
IMPORTANT: To keep rail on
truck secure, make sure clamp
teeth engage grooves on rail,
turn nut finger tight and then use
wrench to finish tightening.
D. With rail flush at top of box and
clamp teeth engaged, tighten clamp.
Check if rail is level. If rail tilts up,
loosen clamp; lower it; engage teeth;
and tighten it. If rail tilts down, loosen
clamp; raise it; engage teeth; and
tighten it.
E. Install second clamp on rail at
midway point of box. Adjust rail flush
at top of box and repeat clamping
procedure, always making sure teeth
are engaged on rail grooves.
F. At tailgate, adjust rail height flush
with top of tailgate. Repeat clamp-
ing procedures placing third clamp
as close to tailgate as possible.
NOTE: For trucks with an elec-
tric tailgate, rails will have to be
installed slightly higher (approxi-
mately 3/16") to eliminate interfer-
ence. Most short box kits contain 6
total clamps. Install 3 per side rail.
For kits with 8 total clamps, install
the 4th clamp between 2nd and 3rd
clamp on each side rail. Repeat
STEP 1 to install rail on opposite
side. When done, make sure all
clamps are torqued to 20 ft-lbs on
both rails.
