What does MBS stand for in rope hardware specifications?

Explanation:
MBS stands for minimum breaking strength—the guaranteed minimum load at which the rope or hardware will fail under standardized testing. This rating is what manufacturers promise under controlled test conditions, serving as the baseline you use to compare gear and set safe working limits. In practice, you design with a safety margin well below the MBS, so you’re never approaching that failure point. The other terms don’t fit standard rope-spec nomenclature. A maximum breaking strength would imply the highest load the item could handle, which isn’t how these ratings are provided; the value given is the minimum guaranteed strength. Measured breaking strain and major breaking strength aren’t the standard design ratings used in rope rescue gear.
