I bought this about 1mos. ago. Since then, I've switched to all Stihl sprayers. This rack will work with all solo backpacks and most SP Systems sprayers (as well as any sprayer that has these same characteristics). $40 TYD (lower 48). Shoot me a PM, if interested. Photos of the sprack can be seen on the Jungel Jim site. The unit photo'd on the site shows a bungee for the securing apparatus. Mine (the new model) has a strap with a male and female clip. Thanks for looking.
