# What is a T-Track?

**What is a T-Track?**
Oval and wing-shaped aerobars typically feature a channel along the top, often covered with a rubber insert. This is commonly known as the accessory channel or T-Track, named after the T-shaped bolts designed to slide into the channel for mounting accessories.

Below is an image of a Rhino Rack Vortex bar, with the rubber inserted into the T-Track. These are removable for accessory mounting, and have the same concept across all of our brands.
