This low-profile molding dresses only the top edge of the bookcase. A compact alternative to our taller crown, suited to smaller rooms, lower ceilings or a minimalist look.
Left and right side trim, modular front sections for the selected configuration, both wall-side end options and installation instructions. Order one kit for a connected row; separate bookcases need separate kits.
No glue or screws required. Lightweight, removable sections install along the top shelf without permanently modifying the bookcase. Wide BILLY is approximately 80 cm / 31.5 in; Narrow is 40 cm / 15.75 in.
For standard BILLY bookcases approximately 11 in / 28 cm deep. Some models are 15⅜ in / 39 cm deep: contact us before ordering if yours is not 28 cm deep. Measure the full outside width and make sure all connected bookcases are level and the same height.
The Etsy options are White, Black Oak Effect, Brown Walnut Effect and Oak Effect. These are solid matte PLA colours, not wood-grain textures. They coordinate with furniture finishes but cannot guarantee an exact match.
Each kit is made for your selected configuration and colour. Small connection seams and subtle layer lines are normal. Check your measurements and compatibility before ordering.
