PRE-INSTALLATION NOTES

(REVIEW ALL OTHER INCLUDED INSTALLATION GUIDES BEFORE BEGINNING)

If you’re installing a rear window protection accessory, mount it prior to mounting the cover.
Some models require bulkhead preparation first. Please refer to the instructions in the bulkhead prep kit prior to mounting the cover.
If your cover includes shims, affix the included bed rail shims first and reference their included instructions.

MOUNT THE PANELS

Place the center panel across the bed, cheated toward the tailgate.
Each panel is tapered front to back. Make sure the arrow on the underside of the panel is pointed toward the tailgate.
Attach the tail panel by holding it at a 90° angle from the bed rails and mate the driver’s side hinge first, followed by the passenger side’s c-shaped hinge.
CAUTION! Be sure all hinges are fully mated before lowering panels.
In the same way, attach the cab panel but start by mating the passenger side first. Make sure the safety catch has been untaped and then lower panel into position.
Position the cover front to back so that the front of the cab panel lines up with the outside edge of the center of the bulkhead. Center the cover side-to-side on the truck.
Position the cap clamps as far apart as possible under the center panel. Attach the center panel by uniformly tightening a cap clamp using a 9/16″ socket to between 5-6 ft lbs.
- While tightening clamps, be aware of possible bed rail cap deformation. Overtightening clamps will damage bed rail caps and cause leaking.
- Retighten after a week of use. Check them every time you haul on top.
- The bottom halves of the cap clamps should be in the track.
  PREP FOR THE LOCK RODS
Unbolt and move one of the bolts of the lock-rod guide brackets to the second, unoccupied slot using a 7/16” socket. Repeat this on each of the cover’s four brackets.
If your plastic bed rail cap extends below the metal edge of your bed rail, trim the excess at each lock rod location so that it’s flush with the metal bed rail’s edge.
ADJUST THE LOCK RODS
Loosen set screws for the tail and cab panel lock rods with the provided hex key and retighten each lock rod after ensuring three things…
CORRECT ORIENTATION
- The Z bend orientation is always maintained
  HANDLE CLOSED
- With the handle in the closed position, the rod tips do not hit the bed walls.
  HANDLE OPEN
- With the lock handle in the open position, the rod tips clear the bed rails.
After properly aligning the lock rods in the closed position, it is time to tighten all brackets using a 7/16″ socket. To ensure a tight seal, it is crucial to simultaneously push up on the bracket AND apply downward pressure on the cover. Repeat for all bracket locations.
- The panels may be tough to open and close at first. Leave the panels closed as much as possible to allow the weatherstrip to break in. After a few days, you’ll find things working smoothly.
- The cab panel has a safety spring lock handle ensuring you engage the lock rods when closing the panel. This helps prevent accidental opening of the panel while driving.
- If you are installing a Cross Bin, do so now. Refer to the Cross Bin Installation Guide for details
  ATTACH THE BED RAIL EDGE TRIM
Peel the red adhesive backing from the edge trim pieces. Affix them to the metal bed rail in the correct orientation at the four points where the lock rods pass underneath.
- Bed rail edge trim protects the lock rod end cap from wear, and helps draw the panels down and compress the weatherstrip. When installed properly, it will be a little tough to turn the lock handle at first.
  ATTACH THE GAS SPRINGS & SAFETY CATCH
Open the cab panel. Have a 2nd person support it in the open position. Loop the end of the cable tethers around the ball stud arms, making sure to go beyond the ball stud and nut.
Attach 2 gas springs to the cab panel.
Make sure the barrel end is up. If you install your gas springs upside down, they’ll fail. If 2 of your gas springs have heavier poundage printed on them, use them here.
Attach the safety catch by pulling down on the panel and pushing the keyhole at the bottom of the safety catch around the nut, making sure to engage the spring clip.
With the safety catch in place, your cab panel will only open partially. To fully open the panel, pull down on panel while using your other hand to push up on the flat part of the catch until it disengages.
Attach the 2 remaining gas springs on the tail panel, again making sure the barrel end is up.
Leave the cover closed and locked for 24 hours to allow the pressure-sensitive weatherstrip adhesive to fully cure.
