The upright that joins two bays. Double uprights go between the bays of a Shelf Space unit, so you can grow from 1 bay to 2, 3, 4 or more. They come in seven heights from 650mm to 2.7m and are pre-drilled every 130mm for adjustable shelves. They're made in South Africa from heat-treated pine and are delivered free anywhere in the country.
Use them to add a bay to a unit you already have, or to build a long run of shelving for a garage, storeroom, shop, office or workshop.
Why customers choose it
- Grows with you: add a bay at any time without starting again.
- Middle support: double uprights carry the shelves on both sides of a join.
- Seven heights: 650mm, 900mm, 1.2m, 1.8m, 2.1m, 2.4m or 2.7m.
- Mix heights: build stepped sections, or use taller uprights at the back and shorter ones at the front.
- Custom heights: we can cut an upright down to the height you need.

Frequently asked questions
Can I get a custom height?
Yes. Order the next standard size up and add the height you need in the special instructions at checkout. For example, for 1,600mm, order the 1,800mm upright. We'll cut it down for you.
Do double uprights go on the ends?
No. The outer ends use single uprights. Double uprights only go where two bays join.
Are screws included?
The screws to fix shelves come with the shelves. If you need loose screws or fittings, WhatsApp us before you order.
