Compare the 41A3589 belt labels

Compare the 7-foot and 10-foot supplier designations with the complete catalog number. Each listing independently names 1270, 1280 and 1280R under its own source conditions. A shared model association does not establish the same physical belt length or replacement equivalence.

Separate references with their own source scope. This comparison establishes no replacement or interchangeability.
