The yellow & black RoboCup Clamp-On Dual-Cup & Drink Holder is a utility patented caddy that securely holds two drinks, tools, fishing poles, drumsticks, phone, keys, and much more by clamping instantly to both round and flat surfaces up to 2" in size.

Removable End Caps    Stainless Steel Hardware and Springs

To open (1) hold the RoboCup with the jaws facing away from you and (2) using both hands squeeze the cups inwards using your chest muscles and (3) clamp onto a surface using both jaws equally.

The two bottom end caps are removable for access to clean the RoboCup and for long objects. Updated in mid-2017, these end caps now have threading with a perfect fit.

Ribs were added to reinforce the clamping jaws in mid-2017 making them twice as durable. The poly material continues to have UV-inhibitors added for longevity against the sun.

The hardware and two powerful springs are stainless steel for rust prevention.

The spring-loaded jaws are very powerful, requiring proper use and caution. Do not put hot liquids in the RoboCup just in case the RoboCup gets knocked free.
