 HEY! TORQUE BOY: READ BEFORE YOU INSTALL DECKED 

1. DON'T go rogue on us, please read the instructions. 5. Start all bolts with fingers to avoid cross-threading.

2. DON'T over tighten bolts, get em' hand-tight. 3. DON'T use power tools. 4. If you don't follow directions and do use power tools:
1). Set clutch at a very low setting. 2). If you blow it: Two extra threaded inserts are included in BAG PREP-EXTRA. That's all you get, unless you call us and ask for more. The inserts will replace any stripped inserts in the tailgate ammo cans and studs or front face of the center vert at the bottle opener, but NOT THE TOP OF THE CENTER VERT, so hand tighten until snug only! You can also screw the inserts back in if dislocated. There is a straight screwdriver slot on the underside of the threaded insert.

6. DON'T over tighten J-hooks during installation. Just get 'em good and snug; enough to keep the system from moving in the bed.
7. You will have leftover washers ­ you're welcome. 8. Nice job if you're still reading .

Prevent embarrassing, expletive-filled language,

watch our detailed installation video or give us a call. We're happy to help!

AMMO CAN DRAIN HOLES (TO DRILL OR NOT TO DRILL.)
· Do you use a tonneau or shell over your DECKED system? There is no need to drill holes, unless you leave your tonneau open in a deluge. · Does your DECKED system live outside? The ammo cans will get water in them. You'll need to drill holes in the ammo cans. There are two dimples in the bottom of each ammo can. Drill a 1/2" hole at each dimple. A smaller hole will get clogged.
