Kettle Gryp® is designed to fit the majority of dumbbells on the market, although there are a few exceptions:
Dumbbell Handle Width and Diameter
The dumbbell handle width needs to be at least 4.5" wide for Kettle Gryp® to fit. Most dumbbell handles are approximately 6.0" wide. Some very light dumbbells may be less than 4.5" wide.
The dumbbell handle needs to be less than 1.5" at its thickest point. The foam insert inside the Kettle Gryp® will contour to both straight and curved dumbbell handles as long as the thickest part of the dumbbell handle is less than 1.5".
Some dumbbells with large or odd shaped weights may interfere with the handle of the Kettle Gryp®. Although the handle of the Kettle Gryp® is a snug fit, the Bowflex SelectTech 552 will fit with no interference from the weight plates. The Bowflex SelectTech 1090 will not fit the Kettle Gryp® when the large inner weight plates are selected.
Portable. Adaptable. Economical.
Kettle Gryp® is a portable dumbbell adapter that turns ordinary dumbbells into dynamic workouts. Perfect for the home gym, traveling fitness enthusiast, or trainer/gym owner with limited space; Kettle Gryp® gives you a full kettlebell workout at a range of weights anywhere you can find a dumbbell.
