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.

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
Step 1: Join the post sections if they come in pieces, then screw a levelling foot or castor into the bottom of each post.
Step 2: Decide the shelf heights and clip a pair of split sleeves around each post at the same numbered groove, narrow end up.
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.
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.
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.
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.
