This billet aluminum bottle bracket looks great and is easy to use. The saddle area that holds the bottle is lined with rubber so your nitrous bottles do not get scratched. The large knurled knobs allow you to quickly secure or remove the bottle without tools. This version is designed to bolt to the floor of the vehicle. For the single bottle floor mounted version, see part number 11108. For the single bottle roll bar mounted version, see part number 11108B
