Every tray starts within the base. Movement is along its own unobstructed lane with the drawer at its normal stop.","A tray deeper than the exposed area cannot become wholly exposed by sliding within that base. No passing through the front wall, tilting route or lifting permission is inferred.","The 29 cm front and 14 cm rear trays, separated by 3 cm, are hypothetical. The rear lane becomes free only after the front group is removed.","The rear tray’s minimum 15 cm shift ends with its back exactly at the covering edge. Moving it 32 cm to the front is a separate illustrated position; grip and vertical removal still require a measured path.","Blox figures refer to the maker’s joined example footprint, not each individual tray. Loaded height and the assembled group’s removal strength remain separate.","Published runner travel does not establish measured exposed depth. Keep drawer stops, interlocks, runners and required restraints as instructed."],"baseDepth":46,"exposed":31,"width":50,"covered":15,"cases":[{"name":"Short front tray","start":0,"depth":29,"result":{"visible":29,"covered":0,"canExposeWithinBase":true,"minimumForwardShift":0}},{"name":"Long front tray","start":0,"depth":40,"result":{"visible":31,"covered":9,"canExposeWithinBase":false,"minimumForwardShift":null}},{"name":"Rear tray before movement","start":32,"depth":14,"result":{"visible":0,"covered":14,"canExposeWithinBase":true,"minimumForwardShift":15}},{"name":"Rear tray brought to the front","start":0,"depth":14,"result":{"visible":14,"covered":0,"canExposeWithinBase":true,"minimumForwardShift":0}}],"blox":[{"name":"43.9 cm front to back","across":26.5,"depth":43.9,"widthDifference":23.5,"result":{"visible":31,"covered":12.9,"canExposeWithinBase":false,"minimumForwardShift":null}},{"name":"26.5 cm front to back","across":43.9,"depth":26.5,"widthDifference":6.1,"result":{"visible":26.5,"covered":0,"canExposeWithinBase":true,"minimumForwardShift":0}}]}
