Every specimen is logged before it touches the floor.

Incoming components are photographed, dimensioned, and assigned a chain-of-custody number. Our fixturing engineers study the OEM mounting geometry and design purpose-built adapters that replicate in-field boundary conditions — not generic clamps.

Fixture drawings are reviewed against ASABE EP496 before any load is applied.
