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.

Adarac Aluminum Series Custom Truck Bed Ladder Rack - Aluminum - 500 lbs - A4001221

Average Customer Rating:  5.0 out of 5 stars   (3 Customer Reviews)

- A4001221

This is a great, sturdy product. I purchased it to carry Kayaks and Canoes on my F150 and it's the only reasonably priced solution I could find that didn't require me to remove my Backflip bed cover. The only drawback is that it uses the stake holes in the bed to attach it and Ford covers the front ones up on the short bed version of the truck. If you have the long bed F150 you won't have any issues. 683549

Review from a similar Adarac Aluminum Series in Ladder Racks

The rack is perfect for hauling our Kayaks. I painted mine satin black before I installed it to better match my truck. 655767

Ask the Experts about this Adarac Ladder Racks

Do you have a question about this Ladder Rack?

  • Dual Kayak Carrier for a 2015 Ford F-150 FX4 SuperCrew with Tonneau Cover
  • In order to carry two kayaks on your 2015 Ford F-150 you can do so on the roof with a roof rack or over the bed with a ladder rack. The ladder rack option will be more versatile and can hold more weight but the roof option will be more cost effective. For a roof rack, I recommend the Rhino-Rack Vortex Aero Crossbar System part # RRVA165B-2, part # RRRLKVA, and part # DK427. This system has aero shaped crossbars for reduced wind noise and locks for security. In order to secure your two...

  • What Ladder Racks Can Fit 2018 Ford F-150 6.5 ft Bed with BAK X4 Revolver Tonneau
  • With the BAK Revolver X4 part # BAK79327 that you have installed on your 2018 Ford F-150 with a 6-1/2 foot bed you can install the sliding Thule TracRac # TH43002XT-501 which would work great. Your tonneau is actually the only one that can fit with this rack and this rack is typically the most desirable option since the uprights can slide forward and back. The Adarac options also will fit like the part # A90630, # A4001221, and # A4000946. These are fixed bar ladder racks.

  • Does the Adarac Aluminum Series Ladder Rack 4001221 Come in Black?
  • The Adarac Aluminum Series Custom Truck Bed Ladder Rack # A4001221 does not come in black but there is a similar option that does and installs in the same way. It is the Adarac Custom Truck Bed Ladder Rack - Steel with Aluminum Crossbars - 500 lbs # A90630. The biggest difference is the angle in which the uprights connect to the base rail and crossbars and the base rail having holes instead of the track.

  • What Ladder Rack and Tonneau Cover Can Fit 2009 Ford F-150 6-1/2 ft Bed
  • Since you have the tops of your bed rails covered with the rails of your tonneau cover there won't be a ladder rack that will fit and work well. You'd have to go with a tonneau cover that fits between the bed rails so that you can fit a ladder rack through the stake pockets. Since we know you have a 2009 Ford F-150 with a 6-1/2 foot long bed the Adarac Aluminum Series ladder rack # A4001221 would fit and you'd need a tonneau cover like the # TX598101 which fits between the bed rails.

  • Best Way to Carry Kayaks on a Adarac Ladder Rack
  • The best option to keep Kayaks stable on the Adarac Ladder Rack part # A4001221 on a 2019 F-150 is the J-style Kayak carrier part # E98878. The J-style carrier is the best option for your setup because the carriers are designed with universal brackets and hand knobs that allow you to adjust the carriers to fit snugly on the square crossbars of the ladder rack. The J-style carriers carry the kayaks on their sides so they take up minimal space on the rack. This...

  • Which Adarac Ladder Rack for 2018 Ford F-150 Can Fit Folding BakFLIP G2 Tonneau
  • Since the tonneau you are interested is a folding style the best option for an Adarac ladder rack will be the Pro Series part # A4000946 which is a confirmed fit for your 2018 Ford F-150 with a 6-1/2 foot bed because the uprights of this rack do not angle in like the Aluminum Series you mentioned does. This allows a folding cover better clearance. The correct BakFlip G2 you'd need for your truck is the part # BAK26327.

  • Adarac Ladder Rack Mounting Rail Dimensions for 2014 Ford F-150 with 6-1/2' Bed
  • The overall width for the mounting rails of the Adarac Aluminum Series Custom Truck Bed Ladder Rack # A4001221 is 2-19/32". From the center of the bolt hole to the inside of the rail is 1-1/8" while that same measurement to the outside is about 1-15/32". I confirmed all of this with my contact at Adarac. So as long as you have 1-1/8" from the center of your stake pocket to the rail for your tonneau cover you won't have any problems with this fitting on your 2014 Ford F-150 with the 6-1/2'...

  • Ladder Rack for 1964 Ford F-250
  • The Adarac Aluminum Series Custom Truck Bed Ladder Rack # A4001221 is a very nice system, though we simply sell them and do not actually produce them. They are custom-made to fit certain year, make and model of truck, and though unfortunately there are none which are going to fit your 1964 Ford F-250, but we do have some options for you. The Detail K2 Flip Rack Fold Down Ladder Rack # K2TFR150 and Yakima Outdoorsman 300 Ladder Rack # Y01137-Y00410 are both clamp-on installations that...
