A Hook to Secure Your Bike Helmet on a Coat Rack This innovative design allows you to hang your Bell Ukon or similar bike helmet on a coat rack with ease, making it simple to store your gear when you come home from a ride. The hook is specifically designed for use with mushroom-shaped pegs found on many coat racks. Simply slide the hook onto the peg and leave it in place, then hang your helmet securely when you're ready to stash it away. With this clever hook, you can easily hang up your bike helmet with the top facing the wall, all while keeping your hands free to doff your helmet in one smooth motion. The hook is designed with the Bell Ukon helmet in mind, but its universal design makes it suitable for other helmets with a similarly shaped hole at the crown. Look for the red marks on the image to see exactly how it fits together. The wall-side hole accommodates pegs with diameters of 8.3 mm and 16.1 mm, along with a thin stem of 16.8 mm.
