Rules for wall and under-table builds

Every hanging build carries its weight from a single top row: that row mounts to the wall or the rail, and each row below hangs from the one above. A few placement notes follow from that.

Sizes: W is width (1W = 88 mm) and H is height (1H = 56 mm, 0.5H is half of that). The collection number - 115, 185, 240 - is the case depth in mm.

5 notesWall and under-tableNo load rating published

Why is there no load rating?

No load rating is currently published. How much a hanging build holds depends on the wall, the anchors, the screw count and the quality of the prints themselves - so the system states the placement rules it can stand behind, not a number it cannot.

What you'll need

Quantities depend on your layout - the Planner works them out for your build, and every official kit lists them exactly.

Each row supports the rows below

When mounted only at the top, each row hangs from the row above. So the bottom case supports its own drawer and contents, the middle case supports itself and the bottom row, and the top case and its mount support the whole stack.

THE CONSEQUENCEEverything you add below adds to what the top row and its screws carry. The wall material, anchors and mounting screws also affect how much the build can support.

Three rows of black cases hanging on a wall, drawers out so the cases show. Each case is labeled with what it supports: the top case all 3 rows, the middle case 2 rows, the bottom case 1 row. The wall mount behind the top row is orange, with an inset showing it screwed to the wall, labeled wall mount

Everything hangs from the orange wall mount

Connected cases brace one another

Connected cases brace one another. Adding a case below extends the structure downward, and the lower case's back bears on the wall, helping resist tipping when an upper drawer is opened. In a build mounted only at the top, the top mount still supports the weight of the whole stack.

WALL BUILDS ONLYThis describes a build on a wall mount, not an under-table build. A case below also adds its own weight and contents to what the top mount holds.

True side view: a wall in section, one black case on an orange wall mount, its pale drawer pulled most of the way out. An arrow under the front of the drawer points down, labeled tends to tip forward — **ONE CASE ALONE** an open drawer puts its weight out in front of the wall mount

The same side view at the same scale, with a second black case connected beneath the first, its drawer closed. A pale line marks where the lower case meets the wall, labeled back bears against the wall — **WITH A CASE BELOW** the lower case, drawer closed, rests its back against the wall

SAME WALL, SAME MOUNT, SAME OPEN DRAWER

Put narrower cases nearest the support

In a hanging build, put 1W and 2W cases in the top rows and 3W and 4W cases lower down. The walls of a case are its beams: a row of 1W cases has a wall every 88 mm, a 4W case only two, and the top row holds the whole stack. A tabletop build stands on its bottom row, so there the narrow cases go at the bottom. This matters for heavy loads. For light contents either arrangement works, and the choice is yours.

A wall build with a 1W and a 2W case on the top row and the wide 3W case, marked orange, hanging below them — **STRONGER HANGING** the 3W case in the lower row, the most walls at the mount

The same three cases arranged the other way: the wide 3W case, marked orange, on the mounted top row with the 1W and 2W cases hanging below it — **ALSO WORKS** the 3W case up top: fewer walls carry the rows below, and it is the stronger way round on a tabletop

THE SAME THREE CASES · THE 3W CASE IS ORANGE

What the top row can be

The mounted row starts at 1H or taller. A 0.5H case has no rear bracket interface, so it cannot hang on a bracket - it still belongs in a wall build, hanging beneath a wall-supported case of the same collection. A wall build is one Collection, and so one depth, from top to bottom.

BRACKET TILESWall Mount Lite brackets come in 1W, 2W and 3W tiles - there is no 4W bracket, so a 4W case takes two 2W tiles or a 1W and a 3W.

The back of a white 2W-1H case: four keyhole-shaped peg slots run across its back wall — **1H OR TALLER** keyhole peg slots in the back wall: it can be the mounted top row

The back of a white 2W-0.5H case: a low back wall with no peg slots in it — **0.5H** no peg slots, so it hangs under a taller case and is not the mounted top row

THE BACK OF TWO CASES

Wall and under-table: shared and different

Both hang from one top row and obey the same placement rules. What differs is the mount: a wall bracket whose pegs the top row hangs on, or a rail screwed to the underside that the top row slides into - and the rail has drawer stoppers built in, so its top drawers need none.

DEPTHA wall build is one depth throughout, always. Under a table, a shallower case can hang beneath a deeper one on Bi-Directional QuickLocks.
