Very simply, a fixed handle that doesn't spin. Yet this still provides a lot of versatility for a wide variety of applications such as, but not limited to: general cable machine handles, exercise band handles, pull up handles, hercules hold handles, sled pull handles, and much more!
The larger the diameter, the more grip strength is needed.
Please note that the handle frame and loop depicted in the photos was a special request. The default frame and loop will be similar to that of the rolling handle.
