Drawer slide rails — the rail thickness decides the width
The slide decides the drawer, not the other way round: a side-mounted pair takes 12.7mm each side, so a 500mm opening leaves a 474.6mm box
This drawing comes from one YAML file. No shape was moved by hand.
Notes in the source (in Japanese)
レールの厚みが、引き出しの幅を決めてしまう。側面付けなら左右に 12.7mm ずつ取られるので、開口 500mm の家具に入る箱の外幅は 500 − 12.7 × 2 = 474.6mm。レールを決めてから箱を作る。 逆にすると、必ず入らない。
2 段引き(3/4)は、奥の 1/4 が残る。 奥行 500mm なら 125mm は手が届かない。書類や工具のように奥まで使うものは、3 段引き(フルエクステンション)にする。
中身はベアリング —— すべり摩擦を、ころがり摩擦に変えているだけ。重いものほど効きが大きい。
耐荷重は「ペア」で書いてある(45kgf/ペア = 左右 2 本で 45kg)。カタログの値は静かに載せたときの値で、開けた所に手をついたぶんは入っていない。
底付けとアンダーマウントは幅を削らないが、下の隙間が要る。
