There’s two easy methods when it comes to measure External Circlips.

1. External Circlips are always listed by shaft size. For example if you have a 30mm shaft you will need a 30mm External Circlip.
2. Or, if you have an existing External Circlip to hand, simply measure the OUTSIDE edge of one side, to the INSIDE edge of the opposite side. Be sure to measure the widest part of the Circlip.
