Attach using the provided two straps and tighten snugly to secure.  Remove all existing straps from the RoboCup before attaching the Plus. 

For a more permanent attachment (not provided), use a stainless steel hose clamp for the top strap but be sure to not over-tighten and use a plastic cable-tie for the bottom strap.   
The position of the Plus can be swiveled around the RoboCup for ideal placement. Tall wall height (4”/101mm) holds drinks securely and the top rim has a wavy design allowing convenient access for shorter drinks.
Double the RoboCup drink capacity by using two RoboCup Plus accessories. 1 included. 
Built with a robust thick wall design with UV-stabilizers added for longevity.  Backed by a “no hassle”  3 year warranty.  Made in USA
