Two clean black rectangles mark the wall at dock four, one at each bumper face. Between them runs a band of scraped concrete, flecks of paint and trailer rub rail still lodged in it. The pads did their job. The scar above them is the record of a height nobody ever measured.
We build loading dock systems: levelers, seals, shelters, and the bumpers that take the first hit. The bumper face goes into the same drawing as the pit and the enclosure, never onto the wall afterwards. Dock bumper height positioning is fleet arithmetic, not habit.

A trailer bed is not a shelf; it is a spring plank that moves. Load it and it settles, empty it and it climbs. An air-ride suspension breathes through the whole shift, and a reefer sits at its own height again. One dock equipment maker gives the movement a name — float. The same notes warn that bumper size and fac
