▼ HEY! TORQUE BOY: READ BEFORE YOU INSTALL THE DECKED DRAWER SYSTEM ▼

DON’T go rogue on us, please read the instructions.
Start all bolts with your fingers to avoid cross-threading – you don’t want to spin out any inserts.
DON’T over tighten bolts, get em’ hand-tight…or you will spin out the inserts.
DON’T use power tools.
If you don’t follow directions and do use power tools, please set the clutch at a very low setting.
Over-torquing or using an impact wrench will spin out the inserts – we’re warning you!
If you blow it, you can screw the inserts back in from the opposite side with a slotted screwdriver.
If you really blow it, we’ve included some repair inserts in the PREP-EXTRA bag – install with a 7/32″ hex wrench. Call us if you need more.
Torque ratings are suggestions – tighten all fasteners until snug.
Prevent 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. Depending on the system, we may have drilled these for you already.
