Used with Thule bike, snowboard or ski carriers, this 3-wing knob fits over the threaded end of a U-bolt or a carriage bolt to help secure the rack to your load bars. Replacement hand knob twists on.

Items arrived as described and tracking information was spot on. Good communication along the way. Thank you so much
The extras part work like the original. And it’s great knowing that etrailer.com carries them individually. Never know what life has in store in the decades the Thule tracks serve you.
Item was of good wuality and an exact f it
These knob are exact replacements for old, worn, broken knobs on your carrier. Can't go wrong with OEM.

product still good 1year later
Very happy with this product, works 100% as it was intended to, fast easy transaction, quick shipping, ill be back for sure!
The three wing hand knobs are the real-deal, I ordered a few extra to have around when or if I lose the others. At that price it's worth it!
Etrailer, YOUR THE BEST! ;)
Part fits perfectly. Lost one of these to road vibration, got four more (just in-case) from etrailer for very reasonable cost. Ordered the longer threaded section for added threaded connection strength.
Thank you for the great service, and always having such a large inventory, even of old parts!
Parts were exactly what I needed. Prices were very reasonable. Shipping was quick and on time. Will definitely keep etrailer.com in mind if I need anything further.

We will be here! Thanks!
Perfect part
Quick delivery - very happy with the product. It was exactly the part I needed.
Perfect! I got the part I needed. Fast and easy.
Fast shipping and great customer service. Fits perfectly.
This part replaces 3-wing knobs on a variety of Thule components. I have used them with the U-bolt assemblies holding old bike trays to the rectangular load bars, and to attach a Thule faring to a load bar. I have come across 3-wing knobs with short and long stems, and these are the long ones. They're required for clearance above some of the accessories, but they also have a tendency to split when screwed down very tight.

still works fine
I have a 25 year old Thule bike rack and one of the knobs broke and the other three were pretty worn, so I ordered 4 new ones. With some technical help, I was able to order the correct ones and they show up promptly and worked great. The etrailer folks are the best. Thanks

Working great!!
One of the three wing hand knobs on my several-year-old kayak rack broke. The new ones from etrailer are an exact replacement. etrailer continues to please!

These wing hand knobs ended up replacing all of the wing knobs that came with my roof rack originally. Good product and good company! What other company cares about how the product is doing a year after purchase? Only etrailer!
Great service. Product came as expected
When looking for trailer parts, rack parts, lighting parts, etc. my family looks no further than etrailer. My boat/trailer was rear-ended, totaling the trailer. With the money from insurance and a great local boat dealer, I found a used trailer on-line in the want ads. Right size but was a roller trailer, not a bunk trailer. With etrailer we found all the parts needed and all within budget to set up the perfect fitting bunk trailer. Need trailer stuff - go to the experts - etrailer
Great service, prompt delivery., reasonably priced!
I only used these for my cargo carrier & bike rack during a cross country relocation.
I got spares because the thule product usually cracks & becomes unusable.
They appeared to hold up but only time will tell. I would definitely order from this company again.
I've had my Thule roof racks for over 26 years now, and these 3 wing hand knobs are very hard to find replacements for. You can always count on etrailer though, to have those hard to find components that the other vendors don't stock, and they'll get your shipment to you in minimal time!
Thank you etrailer!!!
