How to Select the Correct Configuration

Confirm the second-upper position first, then match the complete part number, BLT model and listed specification. Similar frames or dimensions are not sufficient evidence.

Why Correct Selection Matters

The second-upper position is distinct from the standard upper position; do not assume interchangeability.

Why Buy From BOCHU.store

The existing 28 mapped options are organized for position-specific verification.
