Do you have a question about this Accessories and Part?
  • Roof Rack for Winnebago Travato Class B Motorhome on 2017 Ram Promaster Chassis
    The Thule TracRac TracVan # TH29613XT roof rack is designed to work with 2 pairs of the existing roof rack mounts on a Ram ProMaster. If your Winnebago Travato has those existing connection points on the roof, the TracVan ES roof rack would work perfectly for you. I've linked to a diagram showing what the mounts look like, and where they can be found on the roof. From the online photos I've seen, it appears the exterior of the ProMaster is unchanged from the cargo model, so it's very likely...

  • Do the Swagman Roamer LT Roof Rack for Pop-Up Campers and Camper Shells Have Load Stops?
    Hey C.J.! I checked our website and Swagman's and did not see any options for load stops that work with the Swagman Roamer LT Roof Rack for Pop-Up Campers and Camper Shells item # S80510. That's a pretty old video you referenced, so I am guessing they're not available anymore. For a comparable set of crossbars that do have readily available load stops item # RRRLH, I recommend the Rhino-Rack Heavy Duty Roof Rack for Tracks item # RR38NP and item # RTC18. I think this is a far better system...

  • Will Roof Rails Work On a Teardrop Trailer T@B
    I do have an option for you but roof rails won't work very well on a teardrop trailer, even if you were able to get the rails to conform, it's likely the accessories would bind due to the steep angles. Instead, you will need to use artificial rain gutter mounts which is what most other teardrop trailers use from what I found. I have attached some parts below. Rhino-Rack Artificial Rain Gutters part # 739A Rhino-Rack Roof Rack Legs part # RL280S4-2 Rhino-Rack Heavy-Duty Roof Rack Crossbars...

  • Rhino Rack RT-Style Roof Rack Track Installation for 2014 Mercedes-Benz Sprinter Cargo Van
    I spoke with Tony, my contact at Rhino Rack, and he assured me that you will only install the Rhino-Rack RT-Style Roof Track, # RB1800B-2, # RLTF, # RRRTS546, from the outside of your 2012 Mercedes-Benz Sprinter. There is no need to remove your headliner or any of the lights/accessories on the interior. To install the rails, you will need to remove the plugs on your Sprinter's roof with a flat head screwdriver in order to secure the track with the T-bolts provided. You will also need...

  • Roof Rack Recommendation for 2019 Ford Transit T250
    The roof rack I recommend for your 2019 Ford Transit T250 is the Rhino Rack Heavy Duty rack part numbers # RB1800B-2 and # RRRLTPFC-2 because the crossbars of this rack are the best suited option for carrying ladders. The strip on the top channel has a no-slip rubber surface which helps keep them from moving and because the top channel has load stops made for it for this exact purpose. The bars are shaped more like a ladder rack than a roof rack and combined with a set of Rhino Rack Load...

  • Rhino Rack Roof Rack and Pioneer Platform Rack For a 2010 Ford E-350 Van
    Yes, we have the Rhino-Rack Heavy-Duty Roof Rack Crossbars # RB1800B-2 that are held in place with the Rhino-Rack Roof Rack Legs # RL150S10. Or if you are looking for a Pioneer platform the Rhino-Rack Pioneer Platform Rack # RR43QX is the one you need. Both systems attach to the gutter tracks along your 2010 Ford E-350 Van.

  • Best Roof Rack System for 2001 Ford E350 Van
    The gutter mounts we have are actually really sturdy if you get the right ones and install them right. Technically, you should have more weight capacity off the gutter mounts since the weight is distributed vertically through the gutters vs racks bolted onto your fiberglass roof. A good system for your 2001 Ford E350 Van is the Rhino Rack system with Square Crossbars # RB1800B-2 and Gutter Feet # RL150S10. You can switch the square crossbars for aero ones with 71" Vortex Aero Crossbars...

  • Parts Needed for 71 inch Long Rhino Rack HD Roof Rack for Camper Shell
    If you wanted a similar Rhino Rack Camper Shell roof rack to the part # Y01-140B that has 71 inch long crossbars you'd need to piece the kit together with the part # RB1800B-2 for the crossbars, # RTC16 for the tracks on the roof, and then # RRRLT600 for the legs and you'd be set.

  • Compatibility of Rhino-Rack Pioneer Platform on Pace Edwards Ultragroove Tonneau Covers
    The Pace Edwards UltraGroove Metal Hard Tonneau Cover - Retractable - Aluminum - Matte Black # 311-KMTA10A38 and the Pace Edwards UltraGroove Hard Tonneau Cover - Retractable - Aluminum - Matte Black # 311-KRTA10A38 will allow you to install a Rhino-Rack system. I recommend the Track Mount RLCP Legs for Rhino-Rack RTC- and RT-Style Roof Rack Tracks - 2" Tall - Qty 4 # RLTP-2 along with the Rhino-Rack Heavy-Duty Roof Rack Crossbars - Black - 71" Long - Qty 2 # RB1800B-2.

    Yes, you can use a Rhino-Rack Roof Rack with the Thule/Yakima tracks on the Pace Edwards Metal Ultragroove Retractable Tonneau Cover. I have listed the parts you need below: Rhino-Rack Quick Mount Legs part # RRRLT600 Adapter Kit for Rhino-Rack RTL600 Legs part # RRT-FK3 (Yakima) part # RRT-FK1 (Thule) Rhino-Rack Heavy-Duty Roof Rack Crossbars part # RB1800B-2 Roof Rack Leg Spacer Blocks for Rhino-Rack Heavy-Duty Crossbars part # RRQMHD05 (2).

  • What Roof Boxes Will Fit On The Rhino Rack HD Square Crossbars
    You will have plenty of options for cargo boxes that will fit on the Rhino Rack HD bars # RB1800B-2. As a matter of fact you could fit virtually any roof box that we carry. Most cargo boxes are made with universally designed clamps, so they will fit any crossbar shape. The box does not have to be brand specific to the roof rack. So you could absolutely use a Thule or Yakima roof box. My favorite roof box is the Thule Force # TH6357B. This box (like most others) is compatible with virtually...

  • Recommended Rhino-Rack Crossbars That Works With A Retrax Pro Tonneau Cover
    I did some research and unfortunately Rhino-Rack does not make the HD bars # RB1800B-2 compatible with your RetraxPro tonneau cover. The only kit they make that is desinged to be used with the Retrax Pro and Retrax XR tonneau covers is the Rhino-Rack Vortex Crossbars for Retrax XR and Mountain Top EVO-M Tonneau Covers # RRVA180B-RRRLT600. These crossbars have a maximum weight capacity of 220-lbs. measure 71" long x 3-1/8" wide x 1-3/16" tall, and will mount to the t-tracks on your Retrax...

  • Recommended Roof Rack for 2020 Ram ProMaster 1500 to Use Rhino Rack Batwing Awning
    I recommend using the Rhino Rack Roof Rack for 2020 Ram ProMaster 1500 that uses parts # RB1800B-2 and # RRRLTPFD, which will give you a nice and durable roof rack for your van. This rack can be used to mount the Rhino Rack Batwing Awning # RR33200 directly to the Vortex Aero crossbars # RB1800B-2 by using the top channels of the bars, so it's a great choice that gives you a high quality rack at a nice price point. We don't have any fans that would mount to your crossbars but as long...

  • Does the Weight Capacity for the Rhino-Rack Crossbars Reflect Both Bars or Just One Bar
    The 176 lbs weight capacity for the Rhino-Rack Heavy Duty Square Bar Roof Rack, part # RB1800B-2, that you referenced reflects both of the crossbars combined.

  • Solution for Mounting Tent to Bed Rails on 2018 Ram 1500 with Tonneau Cover
    As long as your Access roll-up tonneau cover installs completely inside the bed rails on your 2018 Ram 1500 you can use the Rhino-Rack RT-Style Roof Rack Tracks # RRRTV168. Just note that you may need to cut into the bed liner (if present) where the rivets for the tracks will attach. With the tracks installed you can then use the Rhino-Rack RLTF Legs # RLTF and the Heavy-Duty Roof Rack Crossbars # RB1800B-2 that you mentioned to complete the setup. These crossbars have a combined weight...

  • Recommendation for Attaching Solar Panels on the Roof of a 2010 Ford E-350 Van
    For a roof rack to fit your 2010 Ford E-350 Van, I recommend the Inno Square Crossbars, # INB165, and Inno Feet for Square Crossbars, # INSD. The square load bars measure 65 inches long x 7/8 of an inch tall X 1-1/4 inches wide. The two crossbars have a weight capacity of 220 lbs. The Inno feet # INSD use the rain gutters of your vehicle to attach to the roof. The feet include a special wrench that will allow you to munt the feet to the van. The wrench makes installation quick and easy. For...

  • Rivet Holes on a Rhino-Rack RT-Style Roof Rack Tracks for a 2016 Mercedes-Benz Sprinter 2500
    The Rhino Rack RT Style Tracks, part # RRRTS546 are pre-lined to the existing holes in the roof of the 2016 Mercedes-Benz Sprinter 2500. However, you will need to drill two holes on the rear of each track to install the included rivets. The complete kit for this is: Rhino Rack Heavy-Duty Roof Rack Crossbars, 71 inches long, Silver, part # RB1800 or Black, part # RB1800B-2 2x Rhino Rack RLTF Legs for Rhino Rack RTC and RT Style Tracks, part # RLTF Rhno Rack RT-Style Roof Rack Tracks,...

  • Recommended Rhino-Rack Roof Rack For a 2017 Mercedes-Benz Sprinter 2500 With Factory Side Rails
    For your 2017 Mercedes-Benz Sprinter 2500 with the factory rails I recommend the Rhino-Rack Heavy-Duty Roof Rack Crossbars # RB1800B-2 with Rhino-Rack Quick Mount Legs # RRRLT600, Quick Mount Nuts # RRQMFK11-2 and Roof Rack Leg Spacer Blocks # RRQMHD05-2. You will need to replace the channel nuts that come on the legs for the larger M6 30 mm x 25 mm x 5 mm Zinc Nuts # RR96TB. The Rhino-Rack Roof Rack for Thule and Yakima Tracks # Y01-140B-NT only uses 65" long crossbars and the only recommended...

  • Can I Upgrade To 71" Rhino-Rack Heavy Duty Crossbars Instead Of 59" Crossbars On 2012 Jeep Wrangler?
    For your 2012 Jeep Wrangler Unlimited with hard top, Rhino-Rack recommends using Rhino-Rack Heavy-Duty Roof Rack Crossbars - Black - 59" # RB1500B-2 along with Legs # RRRLT600, Backbone Mounting System # RRRJKB1, and Leg Spacers # RRQMHD05-2. While Rhino-Rack does not suggest using the 71" Heavy-Duty Crossbars # RB1800B-2 that you were looking at, you can certainly use them as long as they are not longer than the widest point of your vehicle which is usually the mirrors.

  • Parts Needed to Add Rhino-Rack Pioneer Platform Rack to 2007 Dodge Sprinter
    We can get you set up with a Rhino-Rack Pioneer Platform rack on your 2007 Dodge Sprinter, and there isn't an option to mount the platform directly to your roof, so you'll need to mount the Pioneer to a Rhino-Rack roof rack. So the exact parts you will need to add the Pioneer to your 2007 Sprinter are the following: - Rhino-Rack Pioneer Platform Roof Tray - 60" Long x 49" Wide # RR35TB - Rhino-Rack Heavy-Duty Roof Rack Crossbars - Silver # RB1800 or Black # RB1800B-2 - Rhino-Rack RLTF...

  • Front & Back Hitches With Accessories For Ultimate Mercedez-Benz Sprinter Van 3500
    The Swagman Skaha 2 Plus Bike Rack with Cargo Carrier # S69SR is definitely the move for you, but if you plan on putting it in the front of your 2017 Mercedes-Benz Sprinter 3500, you'll need a front hitch # 306-X7352. For the back if you have a factory step bumper you'll need this hitch # 75601 and if you have a Standard bumper you'll need this one # 75549. In order to use the Yakima EXO Swing Away Enclosed Cargo Carrier # Y62VR you'll need a class III hitch or higher. If you wanted to...

    I can definitely help you with the same type of setup as part # Y01-140B but currently there aren't any kits that use the 71" Rhino-Rack Heavy Duty crossbars. The parts that you will need are the Rhino-Rack 71" Heavy-Duty Roof Rack Crossbars # RB1800B-2, the Quick Mount Legs # RRRLT600, and the RTC-Style Roof Rack Tracks # RTC16.
