Sable Span Viewport Tamper Strip

The strip bridges a hatch, viewport, cabinet, or inspection plate and records cutting, peeling, heat, and continuity changes. Press it onto degreased metal; the adhesive has a vinegar bite and fails beautifully on coolant film. Rolls belong in a sealed bag with their serial ledger, because loose strips invite counterfeit reassurance. Freight crews use them to settle arguments about who opened what. Wealthier clients pair them with live monitoring. An intact strip proves only that this strip was not disturbed. Poor placement leaves alternate access, while an unlogged replacement can make the innocent look industrious. Sable Span uses black-and-cream labels large enough for old eyes and pressure-gloved fingers, with replaceable hinges instead of molded weakness. It turns up on disciplined freight decks where maintenance gets done on schedule, not commemorated afterward.
