Video Transcript for Adarac Aluminum Series Custom Truck Bed Ladder Rack Manufacturer Installation

Speaker 1: Assembly threaded clamp and alignment plates to cord. Then tie knot at top of cord. Insert channel nuts into rack rail. Insert end caps into both sides of rack rail. Tighten end cap retaining screws. Repeat for remaining rack rail.

While holding knotted end of cord, drop clamp into stake pockets. Line up clamp and alignment plates with stake pockets. With clamp and alignment plates flush against stake pockets, place washer over slotted hole, and turn hex bolt until finger tight. Repeat for remaining stake pockets.For easy removal of internal parts later, make single knot at each end. When complete, fully tight rack rail bolts.

At top of upright, thread hex bolts from bottom into mounting bracket. Leave mounting bracket loose, for now. Repeat for each upright. Measure and record mounting distance between inside rack rails at front and rear locations, as box width may vary. Slide mounting bracket into crossbar channel.

Space bottom of uprights to match measurement recorded earlier. Center crossbar, then turn bolts snug. Then install end caps to both sides of crossbar. Repeat for remaining uprights.Set upright assembly between rack rails. Uprights should fit snug.

Next, align channel nuts with bolt holes in uprights. Thread bolts into nuts and finger tighten. Check for equal distance from box edge to upright. If equal, use ratchet with socket to tighten bolts snug. Repeat for rear uprights.Verify uprights are installed correctly. The crossbar centers without binding between uprights. Then fully tighten all bolts until serrations on flanges are seated tightly.

Ask the Experts about this Adarac Ladder Racks

  • Will Adarac Pro Series Tonneau Cover Fit 2016 GMC Canyon with BakFLIP Tonneau
  • The Adarac Pro Series Tonneau Cover part # A4000950 which is a confirmed fit for your 2016 GMC Canyon is compatible with tonneau covers that install between the bed rails as this rack attaches to the top of the bed rails. I am not totally sure which BAKFlip tonneau you have, but the MX4 part # BAK48125 which fits the 6 foot version of your bed would work with the ladder rack.

  • There are two main differences between the Adarac Pro Series Custom Truck Bed Ladder Rack part # A4000950 and the Adarac Aluminum Series Custom Truck Bed Ladder Rack part # A4001226.

  • Recommendation for Ladder Rack with Over-the-Cab-Extension and Tonneau Cover for 2019 Colorado
  • For either a 2019 Chevy Colorado or GMC Canyon with the 5 foot bed your best option is the Adarac Pro Series Custom Truck Bed Ladder Rack # A4000950 along with the BAKFlip G2 Hard Tonneau Cover # BAK26126. For longer cargo you can then add a roof rack to the cab with the Rhino-Rack Square Bar Roof Rack that consists of # RREB126B for the two 50" Square Crossbars, # RRRLKVA for the 2500 Series Legs, RREB-FK1 for the Square Bar Adapters, and # DK330 for the Custom Fit Kit.

  • Can Adarac Ladder Rack Support Roof Top Tent
  • The Adarac Pro Series Custom Truck Bed Ladder Rack # A4000950 that fits your 5-foot bed 2017 Colorado has a total weight rating of 500-lbs between the two bars so it can be used to support a roof tent so long as the total load of the tent, gear and occupants remains within the rack's capacity. The specific tent's installation hardware will also need to be compatible with the Adarac crossbar dimensions (which are 1-1/2 x 1-1/2-inches) and with their spacing. The page I linked for you...

  • Recommended Ladder Rack and Tonneau Cover for 2018 Chevy Colorado Short Bed
  • I do have an option for you, however we do not currently have a tonneau cover available that will work with the Invis-A-Rack Folding Ladder Rack # DZ951551 on your 2018 Chevy Colorado Short Bed. The inside-the-rail clamping hardware for this particular rack prevents any standard tonneau cover from fitting without interference. For a ladder rack/tonneau cover combo that will work great on your Colorado I recommend the Adarac Pro Series Ladder Rack # A4000950 along with the The BAKFlip...

  • Will the Erickson Truck Bed Ladder Rack # EM07706 Fit on a 2017 Chevy Colorado with Bed Liner
  • If your bed liner on your 2017 Chevy Colorado doesn't move then the Erickson Truck Bed Ladder Rack # EM07706 should work just fine. Liners that move around will need to be removed or modified though since you want the ladder rack as secure as possible. Another option we have that mounts to your stake pockets is the Adarac Pro Series Custom Truck Bed Ladder Rack # A4000950. This is more of a custom fit and features legs that can be repositioned or removed based on your needs. Since this...

  • Can Detail K2 Flip Rack Fold Down Ladder Rack Work with Tonneau Cover on Chevy Colorado
  • Technically you could remove the clamps and bolt the Detail K2 Flip Down Ladder Rack # K2TFR150 to the side walls of your truck bed if you were willing to make the modification to the rack and your truck. This would make it compatible with a tonneau cover that mounts inside the bed rails like BAKFlip G2 Hard Tonneau Cover # BAK26126. Keep in mind, this will void the warranty of the rack and the capacity may be unknown at that point just because it hasn't been tested that way. Because...
