"Other brands" counts machines from other manufacturers that list the same width, pitch and link count; the size page lists them.

Before you order

Fitment can vary by serial number. Some sellers write a variant letter inside the size (320x86Bx49) and list those tracks separately; the second table groups them under the base size, so check the exact listing on the model's page. Measure your current tracks and check your operator's manual. How track sizes are written →
