This part is a replacement for the interior foam of the HYPERBELL clamp. The quantity is one piece of foam. Each clamp requires two pieces of foam.
The foam is simple to replace. The old foam can be pulled out with minimal effort. The new foam is simply pressed into the clamp (no glue or tools required).
Which dumbbells will HYPERBELL work with?
HYPERBELL works with almost all regular and adjustable dumbbells. However, there are some limitations. The length of the dumbbell handle needs to be at least 4.5" long. Most dumbbell handles are approximately 6.0" long. The diameter of the dumbbell handle needs to be less than 1.5" at its thickest point. The foam insert inside the HYPERBELL will contour to both straight and curved dumbbell handles.
HYPERBELL works great with hex dumbbells, Bowflex SelectTech Adjustable Dumbbells (552 and 1090), CORE Fitness, Peloton, JaxJox, MX Select, Weider, and many others.
HYPERBELL does not work with PowerBlock Dumbbells or Nuobell.
