The Hardware (sold separately): Durable contoured arms, as rugged as the more expensive brands. The arm storage lock features a "quick snap" strap for ease of use. A&E's Simplicity Plus' push button arm height adjustment (no handle) is easy to use and blends into the arm for a sleek look. Mounting brackets are the same as the Spirit FX and Fiesta, except they have a mill finish. Single-track slider on inside of hardware channel eliminates binding.
