01
What you can set in the shelving configurator
Start with an open 2×3 shelving preset and adapt columns, rows and depth to your wall. Each compartment can stay open, receive a door or drawer, or use a glass front, so one design can combine books, display and closed storage.
Changes are visible in the live 3D editor before you order. Review the finished width, height and depth, and keep the access and installation conditions of your room in mind.
- Set columns, rows and depth to suit the room
- Choose an open shelf, door, drawer or glass front per compartment
- Use it as a bookcase, room divider or wall shelf
02
Standard dimensions and tube lengths
The system uses nine standard tube lengths from 100 to 750 mm (centre-to-centre) and 25 mm ball connectors with M8 internal threads. The same modular logic can be used for shelves, sideboards and display storage.
Because the layout follows standard lengths, you can review future extensions without assuming that every arbitrary millimetre dimension is available. Confirm the connection and installation requirements for the actual design before ordering.
03
See colours and the configured price live
Each compartment can use a colour from the current palette. The item price is recalculated from the current configuration whenever you change dimensions, fronts or colours; it is not a fixed price claim. Delivery, taxes and the final total for the actual destination are confirmed in checkout.
04
Delivery to your destination
The furniture is made to order. Delivery timing, shipping charges and any destination-specific taxes are shown for the actual destination in the purchase path and confirmed before payment.
05
Brand clarity
Klackjoy is an independent brand and is not affiliated with USM. The grid, connectors and tube lengths described here refer to Klackjoy components.
A modular bookshelf is more than a wall of compartments
For books, compare usable compartment height and depth with the tallest and deepest items you own. For mixed storage, separate display space from the sections you want to close. An open bookshelf and a cabinet with multiple doors can have different usable space and pricing even when their outside dimensions are similar.
Think about future expansion, but confirm the connection and installation requirements of the specific design before ordering. Do not infer a load rating from the fact that the frame is metal. For heavy collections or tall layouts, have the configuration's load and stability requirements checked.
Compare current configurations
Outside frame dimensions in mm, including connectors; feet and castors are excluded. Confirm the finished height before ordering.
