- Sterilite publishes the 18 Qt. Ultra Latch Box (model 1984, item 19849806) at 18 1/8 × 12 1/4 × 7 in outside, length × width × height.
- The file is a box envelope of the exterior dimensions with the lid on; the taper, lid rim, latches/handles and stacking ribs are not modelled because Sterilite does not publish them.
- Interior dimensions are Sterilite's figures measured at the bottom of the tub; the tub tapers, so the opening is larger, but its size is not published.
- True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
