This heavy duty shelf unit is probably the strongest on the market & is great for the garage, shed or home. Each shelf can hold up to 50kg in weight (evenly distributed). The shelf unit is green & comes with ventilated shelves (ideal for use in the greenhouse). The shelf unit is quick & easy to assemble (no tools required) or for a super secure fix you can use the clips supplied to fix the unit back to the wall (minimal tools required). We strongly recommend you screw the shelf unit back to a solid surface especially if loading them with heavy objects. 80cm (31) length x 40cm (16) width x 97cm (38) height.
