Funmo 4Pcs Universal Roof Box Car Van Mounting Fitting Set, Roof Box U Bolts Clamps, Roof Box U Bolts with 8 Heavy Duty Lock Nuts and 2 Bandages, Roof Bar Mounting U Bracket 

Perfect to replace some old rusty roof box clamps for summer adventures. Fitted my old Halfords roof box.

Great roof bar clips

Highly recommend. Rock solid in operation a never gave a second thought over 1600 mile ski trip to alps holding Thule box to aero bars.

The Ubend metal work seemed to stretch out further than the standard holes and had to be squished together. The black rubber pulled up and also the screw caps that go in the middle of the fasteners pop out so have lost some already. That be said kept the roof top box on for our holiday and was half the price of the local car accessory shop that begins with a H!

Straps are the only thing to let the set down

I have an old BMW Mini-branded roofbox, originally produced by Thule. This came with T-track bolts only, that only fit BMW official bars. I've changed out to a VW Tiguan. I've bought the Thule conversion kit at great expense (20mm x 27mm T track bolts) but wanted to try an alternative in case we use the box with another car. This kit is priced favourably in comparison to the one available from the out of town motoring retail store. In comparison, these are clearly aimed at 'aerobar' style roof bars, and have a notch towards the front of the bracket (though can still be used with square bars or other bars). I've struggled with the sizing and holding a tape measure against them. They're billed at 90mm, bolt centre to bolt centre, but the bolts aren't a true U shape and are more like a wide V. You may need to take a file to your roof box depending on the spacing of the existing cut outs. Thule's kits come as 45mm or 80mm U bolt spacing - so if you've got the former, so long as you've got a run of 3 holes you should get your 90mm. In the kit you get 8 wheel heads, 4 bolts, 4 rubbers, and a handy set of stickers to cover any unused cutouts on the bottom of your roofbox. So, check and check measurements again, and be wary of the non-U shape, but otherwise, worth a look.

These are replacements for the fiddly ones I had with the roof box, I have Thule winged bars and these fit just great, so much easier to put on than the old ones.

25 years ago I bought a Halfords roof box but over the years the fixing kit has slowly broken apart. Can you buy replacements for less than the price of a new roof box?? Indeed you can - this universal kit is just perfect. Thick, sturdy steel u clamps with large, easy to do up plastic coated knobs and luggage straps to hold anythign loose down inside the box. Each steel clamp is painted with a high quality black paint finish and looks like it would fit any car roof bar (I have a Citroen C4 and it is perfect for mine). A great way to make your old roof box like new again and stop you hating trying to mount it once the plastic furls have broken off the original clamps. Can't wait for summer to try it properly.
