Review: Exactly what I needed to adapt old Thule 724 Flat Top (92724) Ski Carrier - Posting this since I had a hard time nailing down what I actually needed. I was trying to mount an old Thule flat top carrier (724 I think) to a Rhino Rack aero bar with the t-channel, which I figured would be as easy as just unscrewing the FM1 (Fat Mouth) clamp from the ski carrier and replacing the clamp with a T-channel bolt. I bought the "M6x35mm, 4mm Thickness" version of these bolts with the fully square base. They are the perfect size and worked out exactly how I wanted them to, using the stock Thule wing nuts to secure them inside the ski carrier. It makes it so someone can't remove the Ski carrier without unlocking it, rather than just by hand with the Fat Mouth clamp. It also saves me about 1" of height on my Jeep which doesn't sound like a lot but can make all the difference in some parking garages. It took me only a few minutes to swap everything. I took the picture after I had mounted the rear rack but before swapping the front rack to illustrate exactly what I was working with for anyone else who was facing the same situation. The other unexpected benefit was that I was able to slide the ski carrier all the way to the end of the bars making it easier to get skis in and out. The second picture shows both racks changed out.
Review: Perfect fit - Perfect fit for my Volvo slotted cross bars (made by Thule). Stainless steel will not rust like my DIY metal. I’m so pleased with this product. Thank you
