Perfect! I got the part I needed. Fast and easy.
Quick delivery - very happy with the product. It was exactly the part I needed.
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
Perfect part
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!
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!
Thank you for the great service, and always having such a large inventory, even of old parts!
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.

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.
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.
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! ;)

Fast great service
Exactly what I needed/ordered
My brother lent me his car top carrier. He had lost one of the knobs and substituted an awkward wingnut. Before I returned it I was going to replace the wing nut with another knob. Looked for so long until I found etrailer. Ordering and shipment was smooth and prompt. Knob fit perfectly. Thanks

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!
