Built around a custom high-strength polyester webbing harness sized for up to a 10" slam ball. Buy it with our recommended Rep V2 or Rage slam balls, or use your own. Added retention straps lock the ball securely in place for confident throws.

The polyester straps are 4,500 lb and 12,000 lb rated, non-stretch, water-resistant, and far more durable than nylon or cotton. Safe for indoor gyms and outdoor grass—no floor damage, no divots, and easy to clean. A stainless-steel swivel and heat-cured painted handle complete the system.

Indoors, it lands with a controlled “thunk” instead of a bang. The slam ball absorbs impact, reducing bounce, roll, and noise while protecting gym floors and mats.

The handle is made from 3/8" 1144 Stressproof steel (100,000+ psi yield strength), with a fully welded solid steel triangle for maximum durability. Nylon shoulder washers provide smooth rotation, with spares included. Shoulder bolts secure with a 5/16" wrench for reliability (use purple Loctite—never red).

D-rings distribute strap wear evenly, unlike traditional O-rings that fail at the edges.

An ideal practice implement: affordable, durable, quieter, and safer than traditional weights. Slam balls use sand instead of lead and are easily replaced if worn.

Tradeoffs: approximately 1.8 lb heavier and slightly longer than regulation, but the added weight and length largely offset each other, resulting in a feel close to a competition weight.
