Great communication, fast shipping and the best prices

Good product but I never used it it’s still in a box. Bought the wrong part but I thought maybe I can use it some other day in the future because most of the parts in this fashion or universal.

Very impressed about how well this product worked with the topper I purchased!

  • Dimension Pictures of U-Bolt From Kit RUBK-MF
    The U-bolt size of the part # RUBK-MF is what you mentioned seeing in the attached picture. The knobs are larger so it might make them look smaller when looking at the product pictures. Larger u-bolts are not available and if they were they wouldn't fit the cargo box this was intended for.

  • What are the Dimensions of the U-Bolt in Rhino-Rack Heavy-Duty Crossbar Fit Kit # RUBK-MF
    I went in the warehouse and measured the U-bolt from Rhino-Rack Heavy-Duty Crossbar Fit Kit , part # RUBK-MF. The width from center to center of the U-bolt is 2-5/8 inches. The height of the U-bolt is 3-5/32 inches. The amount of thread on each bolt is 2-3/32 inches. The U-bolt diameter is 6 mm or 15/64 inch. I am including a picture of the U-bolt with the dimensions listed.

  • How Wide Are The U-Bolts Included with the Rhino Rack Heavy-Duty Crossbar Fit Kit RUBK-MF
    The u-bolts that come with the Heavy-Duty Crossbar Fit Kit for Rhino-Rack Master-Fit Rooftop Cargo Box part # RUBK-MF are 2-5/8" wide which you can see in the attached photo. This measurement is taken from the center of each bolt and the bolts are 15/64" diameter so if you need the width outside to outside then that would be 2-55/64" or 2-25/64" for the inside to inside width.

  • J-Hook for Attaching Cargo Box to Cargo Carrier
    The knobs of the Heavy-Duty Crossbar Fit Kit # RUBK-MF would only thread about half way down the threaded portion of the u-bolt. A better choice might be the part # UWSJBOLT which is normally used to attach truck bed tool boxes to the bed by the bed rails.

  • Replacement Mounting Brackets for Rola Roof Cargo Basket 59504
    The Rola Replacement Roof Mount Bracket Assembly # 59506, which is the replacement mounting hardware for the Rola Roof Cargo Basket # 59504, does come with both brackets and u-bolts that fit those brackets. It sounds like you may be looking for other u-bolts that are 6 inches long, but there are none because rooftop cargo baskets are made for roof racks, and those bars are, at most, up to 4 inches, but even that width is rare.

  • Is Mounting Hardware Available To Fit Yakima Space Case Roof Box On Chevrolet Traverse Crossbars
    We do not offer a mounting kit that will work with the Spacecase 20 roof box you have. I spoke with my contact at Yakima and they no longer offer a replacement mounting kit for that series of roof boxes. If you wish to replace the roof box with a newer model I recommend the Yakima SkyBox 18 Rooftop Cargo Box, part # Y07336. I have confirmed this box will work with the crossbars you said you have on your Traverse roof rack. I have attached a link to a product review video you can check out.

  • Compatibility of Round Cargo Box U-Bolts with Square Roof Rack Crossbars
    Its easy to modify a cargo box to fit a new vehicle that has differently-shaped roof rack crossbars. However you may not need to do anything to get your Karrite Explorer cargo box's hardware to work on your vehicle with square cross bars. It is perfectly okay to use rounded u-bolt hardware like # 1755892 on a square bar. The replacement hardware kit # SR05587 that we offer for your Explorer cargo box actually uses rounded u-bolts. As long as you can tighten down the hardware you have...

  • Does the Rhino-Rack Roof Rack # RLZ01-DC Install Completely Level on My 2010 Ford Transit Connect?
    Great question! I went ahead and called my tech at Rhino-Rack, and she confirmed that the reason why there are two different heights of legs that come with the Rhino-Rack Roof Rack # RLZ01-DC is because of the curvature of the roof. She also said that the crossbars will be even once installed, so the cargo box will lay completely flat. I went ahead and attached a picture of this rack installed to give you perspective. For a great cargo box that is compatible with the larger Heavy-Duty...

  • Will Yakima SkyBox 21 Fit on Rhino-Rack Heavy-Duty Roof Rack Crossbars
    The max dimensions for a crossbar that the Yakima SkyBox 21 # Y07337 can accommodate is 3-1/2" x 1-11/16". The Rhino-Rack Heavy-Duty Roof Rack Crossbars # RB1250B-2 are a little too tall for that so if you want to stick with Rhino-Rack you need the Vortex crossbars like part # RRVA137B-2. If you let me know the year/make/model of your vehicle I can make a roof rack recommendation for you. The Rhino-Rack HD bars are much taller than typical crossbars so none of the Yakima boxes will work,...
