This cupholder will fit into any vertically mounted L-Track and holds Nalgene bottles, coffee cups, or other large containers! Easy to mount and remove in order to move to different spots on the L-Track. The inner diameter of the holder is 3.75" and can accommodate any container up to this size.
To mount on the L-Track, center the two circles on the back of the holder with two of the circular openings on the L-Track and push inward until the holder is against the inside of the L-Track and slide the holder down to secure it.
