Under-Table Rails

Screw the rails to the underside of a desk or shelf - every case slides into them, and every row below hangs from the row above. Step 1 is the only step with screws.

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.

Tools and preparation

Drill + driver, and an awl or punch if you plan to pre-drill
Wood screws for the rail - see the screw note below before you buy

Surface thickness and screws

The default is a #6 × 3/4" wood screw. Check the thickness of your surface first and pick a screw that cannot break through the top. On hard surfaces it can help to pre-drill: mark through the rail holes, tap a small divot with an awl so the bit does not wander, then drive the screws.

What you'll need

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

Mount the rail under the surface

Hold the rail against the underside and drive the wood screws up through its countersunk holes.

PLACEMENTSet the rail square to the front edge of the surface, its front flush with the edge - the drawer faces finish just proud of it. Wider rows butt their rail tiles end-to-end in line.

SCREW LENGTHDefault is a #6 × 3/4" wood screw - check your surface's thickness and choose a screw that cannot break through the top.

Fit the QuickLocks, slide the case in

Drop a QuickLock into each side channel, then slide the case straight into the rails until both click up.

SPRING TIPThe QuickLock drops in easily - if it catches, guide the springy end with a finger as it seats.

USING MAGNETS?Seat each case's back magnet before it slides in - you can't reach it once the case hangs. Magnet closures →

Hang the rows below

The underside of every case carries the same grooves as the rails - slide the next case in exactly the same way. No screws between cases.

Drawers in

If stoppers sit above the drawer, a level push bumps into them: tilt the front up about 15 degrees, start the back end in under the stoppers, then level it out and slide it flush. With nothing above it, the drawer slides straight in.

MAGNET CLOSURESOptional magnets pull the drawer shut. Match each drawer magnet's polarity to its case magnet - reversed magnets repel the drawer. A pin through the hole in the floor pushes a misplaced magnet back out. Polarity, in full →

Removing a case

Take the drawer out, press both QuickLocks down, and pull the case straight out of the rails.

CHECK THE QUICKLOCKSThe small slots on the case flank show the QuickLock tab - use them to confirm it is engaged, or reach a small hex key in to pull a tab down.
