Step-by-step assembly
Step 1
Start with your assembled BILLY bookcases.
Sold separately. Shown: an 80 cm bookcase on each wall and a 40 cm one across the corner.
Step 2 · manual step 1
Slide a corner fitting under the front of the bookcase side.
Tip the bookcase slightly, then lower its side onto the fitting.
Step 3 · manual step 1
Do the same at the other joint.
Step 4 · manual step 2
Lift the corner bookcase in between.
Its sides go into the second channel of each fitting.
Step 5 · manual step 2
Lower it into the fittings.
The sides of the two bookcases now stand side by side at the front.
Step 6 · manual step 3
Join the tops with the 2 connecting bars (115257).
2 screws (100362) per bar, with the Phillips screwdriver.
Step 7 · manual step 4
With BILLY height extension units:
At most one per bookcase. The bars then go on the extension tops instead.
Step 8 · manual step 4
Join the extension tops with the connecting bars.
2 screws (100362) per bar.
Step 9 · manual step 5
Fix the angle bracket (102715) inside the corner extension.
Make a hole with the awl, then 1 screw (109534) down and 1 into the back panel.
Tips & safety
- Only one height extension unit per bookcase. Never stack two extension units — see the manual, page 6.
- Fix every BILLY bookcase to the wall. Use the wall fixing shown in each bookcase’s own manual.
