Massive 80 × 80 × 3 mm (outer) and 60 × 60 × 3 mm profiles with welded plates (inner) ensure a rigid and secure connection to the base upright.
Evenly spaced mounting holes with 50 mm spacing and 17 mm diameter (25 mm on the side walls) enable easy customization of add-ons and accessories.
Quick installation using an insert piece and 4 bolts extends the structure by 100 cm while maintaining the same load rating as the base upright.
The MARBO SPORT extension is a key element of the modular Monkey Rigs system for commercial and home gyms alike. Thanks to its robust steel construction with precise mounting holes and welded plates on the inner section, the joint is extremely rigid and reliable, and withstands the same load as the base upright.
Installation is simple: the extension is connected via an inserted structural piece and secured with four bolts. The result is a height increase of the structure by 100 cm, opening new possibilities for functional, strength, and circuit training. The finish in red gloss with a powder coat ensures long service life and resistance to wear.
