This is the shortest version in the Erzi roller-slide line. Comprising a total of 17 rollers, the slide can be hooked into a DIN wall-bar unit or attached to a trapeze trestle. Placed on the floor, it provides plenty of scope for exercise. The side pieces are constructed of coated plywood. The rollers themselves are made of sturdy foam material, easily kept clean and replaceable. Note: This is not bulk waste material!
Matches with a diameter of the ladder rungs of 35 mm.
