Our XF 80 Kettlebell rack works with the XF Rack and Rig collection. For racks, select the 1100 mm piece while either length is appropriate depending on rig design. The storage accessory pieces can also be used as components to build custom storage with Eleiko XF Leg options. The 1100 mm rack can store 6-8 black Kettlebells ranging from 4 kg to 12 kg. The 1720 mm unit can store 7 competition kettlebells or one of each black training kettlebell ranging from 4 kg to 20 kg or 24 kg to 56 kg. Two shelves are required to accommodate a full set of black kettlebells.
