How to Select the Correct Variant
Confirm the upper position and D21.5×2 size, then match the original part number and BLT model. Power is a supporting cross-check, not the primary selection method.
Why Correct Selection Matters
Four configurations share the same D21.5×2 dimensions. The same dimensions do not establish interchangeability.
Why Buy From BOCHU.store
The four listed part-number and BLT model groups are shown together for verification before ordering. If the original part number is unclear, use the package label or cutting-head nameplate for confirmation.
