box jump sizes crossfit

Capacity varies by construction and model; in these listings capacities range roughly from 150 lb up to about 500–550 lb. Because capacity depends on materials and frame design, check each product’s listed weight rating for the specific model you’re considering.

Common anti-slip features include textured rubber tops, silicone or PU leather covers, anti-slip PVC surfaces, non-slip rubber feet, and Velcro or hook-and-loop straps on stackable sets to keep pieces aligned. These surface materials and feet improve traction and stability during box jumps and other plyometric moves.

All three formats appear in the listings: multi-piece stackable sets (separate boxes that lock together), single 3-in-1/flip boxes with different heights on each side, and soft foam preassembled boxes designed for safer landings.

Assembly varies by construction: steel- or framed-style sets often require some assembly (many list 'Adult Assembly Required' and may include basic tools), while foam boxes and preassembled flip boxes typically arrive ready to use with no assembly needed.

Many covered boxes have waterproof PVC or PU surfaces that can be wiped clean with a damp cloth; some models also feature removable outer covers (often with hidden zippers) for deeper cleaning.
