INSTALLATION INSTRUCTIONS AND OWNER’S MANUAL
Thank you for purchasing the Velocity by LEER™ roll-up, soft tonneau cover. At LEER, we made sure it offered innovative
patented and patent-pending features you couldn’t find anywhere else, such as our CYNCTM pinch latching system that
locks the cover down. With CYNC pinch latch system, you can quickly pop the cover open from either side of the bed.
As a result, Velocity by LEER is simply unmatched along with its superior materials and craftsmanship. With proper care,
your tonneau cover will provide years of service and enjoyment.
It is recommended you take time to read these instructions before installing this cover even if already familiar with the
product. Often improvements are made without prior notice. Always handle the cover and components with care to
avoid damage.
Before using this product, read the operating instructions, maintenance and safety sections of this owner’s manual and
save for future reference. Your new LEER® tonneau must be registered to make the warranty valid. Registration
information can be found on the back page.

INSTALLATION INSTRUCTIONS
1) INSTALLING COVER SIDE RAILS
NOTE: Some installs require drilling/bolting.
Those kits will contain special side rail instruc-
tions. Follow those instructions for rail attachment
in conjunction with instructions in this owner’s
manual.
NOTE: For trucks with an electric tailgate, rails
will have to be installed slightly higher (approxi-
mately 3/16”) to eliminate interference.
A) Position side rail with attached weather strip
against the inside lip of the bed. Push rail forward
until it touches front of bed. End of rail with nylon
strike towards the rear.
B) At front, adjust top of the rail flush with top of
bed and it there with assistance of another person
or with a spring clamp.
C) Install first clamp as close to the front of the
bed as possible and use 1/2” wrench to tighten.
♦IMPORTANT: To keep rail on the truck securely;
before using the wrench on the clamp, make sure
clamp teeth engage grooves on rail, hand-tighten
the nut and then use wrench.
D) With rail flush at top of the bed and clamp teeth
engaged, tighten the clamp. Check if the rail is
level.
♦If the rail tilts up, loosen the clamp, lower it,
engage the teeth, and re-tighten it. If the rail tilts
down, loosen the clamp,
raise it, engage teeth and re-tighten it.

INSTALLATION INSTRUCTIONS
6) INITIAL OPERATIONS AND ADJUSTMENTS
A) Unroll cover and place rear bar into strikes
on side rails. Press down on bar to close (20-
30 lbs. pressure). The cover fabric may be
tight. Over time under tension it will conform
to its hardware and loosen slightly. If bar is too
hard to push down, adjust tensioners equally
as needed to close.
B) Close tailgate slowly - top of tailgate should
fit snug under cover bar. If tonneau cover
hampers normal tailgate operation raise rails
by loosening rear clamps; adjust rails up; and
tighten clamps. If there is too much space
between tailgate and cover bar, lower rails by
loosening rear clamps: adjust rails down; and
retighten clamp. Refer to page 10 for trouble-
shooting tips.
♦IMPORTANT: When done, go back and dou-
ble check each clamp and make sure it is
fully tight. Start behind cab and work towards
tailgate.
C) Check cover tension by releasing dual
pinch latching system and open and close
rear bar several times. It should snap down
when closing. Cover fabric should be tight
with no sagging between the bows. If adjust-
ment is needed, roll cover open and to loosen
turn tension adjuster Clockwise. To tighten
turn tension adjuster Counter-Clockwise. Al-
ways turn Dials in Equal amounts.
D) When done, always seal both sides of
cover with hook and loop system. For detailed
operating instructions refer to page 8.
★ TIP: Reasons to keep cover drum tight;
Lasts longer, less noise, and looks nicer.
