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

Do you have a question about this Ladder Rack?

  • What Ladder Rack will Work with the BAKFlip MX4 Hard Tonneau Cover on a 2018 Ford F-350
  • I do have options for you but the Thule TracRac SR Sliding Truck Bed Ladder Rack part # TH43003XT-000 won't work with the BAKFlip MX4 Hard Tonneau Cover part # BAK48331 on your 2018 Ford F-350. The reason for this is because the uprights on the ladder rack are angled inward and the folding slats on the MX4 would come into contact with the uprights when lifted. You may be able to open the first slat if you moved the rear upright all of the way forward but this is surely not ideal. Instead,...

  • What Ladder Rack Will Work with the BAKFlip MX4 Tonneau Cover on a 2020 Ford F-350 Super Duty
  • We do have a ladder rack solution for your 2020 Ford F-350 Super Duty with the BAKFlip MX4, part # BAK48330 for short bed or # BAK48331 for long bed, but you are correct that the vast majority out there use a clamping system which makes them incompatible with most tonneau covers. For your application you can use the Adarac Pro Series Ladder Rack, part # A4000952 for short bed or # A4000958 for long bed, because it uses an anchoring system with the stake pockets instead of a clamping...

  • Ladder Rack and Tonneau Cover Options for a 2019 Ford F-350 Super Duty
  • The Thule TracRac SR Sliding Truck Bed Ladder Rack part # TH43003XT-000EX will fit on your 2019 Ford F-350 with the tonneau cover that you have now. However, the rearmost rack would need to be slide forward in order to open the panels on the tonneau cover because the uprights on the rack are angled in which is not ideal. Therefore, a better option for you if you wanted to use the above is the BAK Revolver X4 Hard Tonneau Cover part # BAK79331. This cover will not interfere at all with the...

  • Best Ladder Rack to Fit with BAKFlip MX4 Tonneau Cover on 2020 Ford F-350
  • The best ladder rack for you to use with the BAKFlip MX4 on your 2020 Ford F-350 is the Adarac Pro Ladder Rack, part # A4000952 for short bed or # A4000958 for long bed, because the legs for the ladder rack sit upright so that you can open and close your BAKFlip MX4 without having to make any adjustments to the ladder rack. The Adarac Pro is made of aluminum so it will withstand the elements much better than other options plus it have the ability to slide along the base rails to accommodate...

  • Adarac Pro Series Custom Truck Bed Ladder Rack for a 2017 Chevy Silverado 1500
  • The reason that the Adarac Pro Series Custom Truck Bed Ladder Rack # A4000958 isn't confirmed to fit your 2017 Chevy Silverado is because it is custom-tailored for 2017-2020 Ford Super Duty pickups. For your Silverado 1500 you need part # A4000963 for a 5-1/2' bed, part # A4000948 for a 6-1/2' bed, or part # A4000949 for an 8' bed. This is the exact same ladder rack, just with the parts that make it compatible with your pickup.

  • Will the Adarac Pro Series Ladder Rack Work On a 2018 Ford F-250 Long Bed with BAKFlip G2 Cover
  • Yes, the Adarac Pro Series Custom Truck Bed Ladder Rack part # A4000958 is the one and only tonneau cover that will work on your 2018 Ford F-250 with the BAKFlip G2 Hard Tonneau Cover part # BAK26331. The rails for the Adarac Pro Series are very slim and only need a very small amount of space to mount atop the bed rails which the BAKFlip G2 allows so you won't have any fit issues I can assure you. The reason the Adarac Pro Series works so well is because the uprights are straight which...
