This is a modular tool rack. Based on specific needs, it is possible to choose between 4 different horizontal shelves:

4141 Balls Shelf (medicine ball shelf) 4142 Angled Shelf (inclined rubber shelf for dumbbells) 4143 Flat Shelf (universal rubber shelf; e.g. kettlebell holder) 4144 Bumpers Shelf (bumper disc holder shelf)

The shelves must be supported by columns:

4140 Upright Column Kit.
4139 Mini Upright Column Kit

Two kits are needed to make up the basic single-bay shelving, which can then be extended by adding other kits. The kits are sold individually so as to be able to compose, as desired, shelving with 2, 3, 4, 5 bays.

For example, to make a 5 bay shelving, like the one reproduced in the image above, 6 Upright Column Kit.
