The legs are independently adjustable for ease of installation in uneven trunk floors. The CNC machined billet aluminum release knob does not require any tools so bottle changes can be performed in a snap. The brackets also include the NOS logo on top of each one so you can proudly show off that you run the best nitrous products available.
