Questions

How many cam locks does the BILLY 80×28×202 use?

Twelve cam locks, part 119081, and twelve cam bolts, part 118331. The bolts screw into the sides; the locks go into the top, the bottom and the fixed shelf and turn onto the bolts’ heads.

Which way round do the panels go?

The bare edge of the top, the bottom and the fixed shelf goes to the back, on the same edge as the curved cut at the foot of each side. The top’s round holes face in, towards the shelves.

Why is the back panel folded?

It comes folded in three along its length so that it fits in the box. Unfold it flat, lay it on at the bottom end and slide it up into place.

Do I have to fix BILLY to the wall?

Yes. IKEA says it must be fixed to the wall with the two brackets in the box, so it cannot tip over. The wall screws and plugs are not included: use ones that suit your wall.

What tools do I need?

A flat screwdriver, a cross-head screwdriver, a pencil, a hammer and a ruler, as the manual shows.

Safety

Furniture that tips over can cause serious or fatal crushing injuries. IKEA says this bookcase must be fixed to the wall with the brackets in the box. Wall screws and plugs are not included: use ones that suit your wall, and ask a professional if you are not sure.

About this guide

The steps, the part numbers, the counts and the order come from IKEA's assembly manual AA-1823127-9 (2024-03-25). The outer size, 80 × 28 × 202 cm, is IKEA's published size. Panel thicknesses, hole positions, the shelf heights and the brackets are read off the drawings, so they are close, not measured. The 3D runs faster than real hands do.

Each shelf holds up to 30 kg, according to IKEA.

The manufacturer's instructions are on IKEA's product page (PDF). If something here differs from the manual in your box, follow the manual.

The 3D models, drawings and text are our own. IKEA and BILLY are named only to say which product this guide is for.
