Where we make the coupler in that size, the weights come from the machine class in our coupler tables. A code marked * is a coupler we do not make: its band is the machine class of the attachments we build for it. Morin sizes and the other interface pages show the band published for them. Your bracket is confirmed with your quote.

How to measure your coupler

Drawing of a bracket with the pin diameter (1), the pin centre distance (2) and the ear width (3) marked

Not sure which system it is? Three measurements tell us which bracket you need.

Measure the diameter of both pins.
Measure the distance between the pin centres.
Measure the width between the inside faces of the ears.

If the coupler has a make or type printed on it, send that too.

Not sure? Send us a photo of the coupler
