How to assemble a wire shelving unit

Chrome or coated wire shelving is built from round posts and wire shelves held by tapered plastic split sleeves. There are no screws: the shelves wedge onto the sleeves under load. It goes together fast, but every shelf must be seated evenly or the whole unit leans.

  • Rubber mallet
  • Spirit level

Parts to check first

Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.

  • Four round posts, often in joining sections
  • Wire shelves with tapered corner collars
  • Plastic split sleeves
  • Levelling feet or castors
  • Wall tie, if supplied

Step by step

  1. Step 1: Join the post sections if they come in pieces, then screw a levelling foot or castor into the bottom of each post.

  2. Step 2: Decide the shelf heights and clip a pair of split sleeves around each post at the same numbered groove, narrow end up.

  3. Step 3: Lay one post on its side and slide the first and last shelves over it, then add the other three posts to form a frame.

  4. Step 4: Stand the unit up and push each shelf down onto its sleeves, then tap every corner down with a rubber mallet, working round evenly.

  5. Step 5: Add the middle shelves the same way, check level, and adjust the feet or re-seat any shelf that sits low on one corner.

  6. Step 6: If there are castors, lock them; for a tall unit, fit the wall tie before loading.

Common mistakes

  • Fitting the split sleeves upside down, so the shelves drop straight through.
  • Putting sleeves at different grooves on each post, leaving a sloping shelf.
  • Rolling a tall, loaded unit on castors, which can tip it.

Safety notes

  • Respect the per-shelf weight limit, load the heaviest items low, and tie tall units to the wall.
  • Lock castors whenever the unit is standing, and unload it before moving.

This is general guidance for this type of product. Your product's own manual comes first: follow its order, fittings and torque values where they differ from this page.
