Explosive Power with Unyielding Stability
The GravoMax Wooden Plyo Box 3-in-1 provides a rock-solid platform for your explosive lower-body training. First, we build this box using premium 18mm thick wood. Next, it utilizes an advanced whole-panel internal bracing system. Because of this highly structured support, the box never wobbles or deforms under extreme loads. Therefore, you can execute heavy step-ups and explosive box jumps with absolute confidence.
Safety and versatility are our top priorities. For instance, we use exactly 37 countersunk screws to assemble the panels. Furthermore, this specific design ensures the screw heads sit below the wood surface, creating a completely smooth finish. Consequently, you avoid painful cuts from protruding metal. Finally, you can instantly switch between 50cm, 60cm, and 75cm heights simply by flipping the box. Thus, you easily change your workout intensity without needing multiple pieces of equipment.
Key Performance Features
- 300KG Weight Capacity: The premium wood offers incredible strength. As a result, you can jump boldly without fear of breaking the box.
- 37 Countersunk Screws: The specialized screw placement firmly locks the boards together. Therefore, it significantly extends the lifespan of the box.

Frequently Asked Questions (FAQ)
Does the box require assembly?
Yes, it is shipped flat-packed. However, assembly is incredibly straightforward. It comes with pre-drilled holes and exactly 37 countersunk screws. Therefore, the interlocking puzzle-style edges fit together perfectly in minutes.
Why are countersunk screws important?
They keep the surface completely smooth. Because the screw heads sit below the wood, nothing protrudes. Consequently, you avoid scratching your skin or snagging your clothes while training.
Is it stable on the tallest (75cm) setting?
Absolutely. Because the box weighs a hefty 22kg and features a whole-panel internal support system, it maintains extreme stability. As a result, it will not wobble or tip over during aggressive jumps.
