The YakAttack RotoGrip Phone Holder Pro stands out with its innovative design and popular RotoGrip technology, offering quick one-handed operation. It features two adjustable rubber wheels that securely hold most smartphones, with width settings ranging from 2.75” to 3.625” and thicknesses from 0.303” to 0.625”. This model includes a Universal Smartphone Harness and Tether, a LockNLoad Mounting System, and a 5” extension arm for versatile adjustments, with a maximum height of 10.5”. The LockNLoad Mounting System is compatible with all YakAttack GearTrac, MightyMounts, and most factory-installed kayak track systems. A built-in 1” ball system allows easy articulation and adjustment of the phone holder's width and position. To adjust, pull against the ball to release the spring-loaded mechanism and twist to fit your phone. Ensure your phone is securely held by adjusting the arms so it rolls firmly into place with one-handed operation. The Universal Smartphone Harness and Tether feature a flexible silicone interface for devices with or without cases, keeping your phone snug. It includes a coiled steel tether (9" coiled, 48" fully stretched) with a locking carabiner for added security. The harness allows easy phone access without blocking the camera lens.
