Join bays of different depths. The Reducer Shelf is a 900mm-wide pine shelf that changes one bay's depth to another, for example from 300mm to 400mm. It lets you line up a deeper bay with a shallower one, without replacing your unit. It's made in South Africa from heat-treated pine and is delivered free anywhere in the country.
Use it for stepped-depth shelving, to fit around a wall, corner, counter or machine, or to adjust a unit you already have.
Why customers choose it
- Mix depths in one unit: run a deeper bay next to a shallower one and keep everything lined up.
- Upgrade, don't replace: adjust the unit you already own instead of buying a new one.
- Clean fit: precision-cut to fit Shelf Space uprights neatly.
- Every combination: any change between 300, 400, 500 and 600mm.
Which option do I need?
There are 12 options covering every change between 300mm, 400mm, 500mm and 600mm deep, in both directions (for example 300mm to 400mm, or 400mm to 300mm). Choose the depth you are going from and the depth you are going to. Every option costs R248. Not sure which way round you need? Send us a photo and we'll tell you.
