Balancing a set of rods means matching the big ends to each other and the small ends to each other, not just the total weight, because where the mass sits changes what the crank feels. This fixture supports one end of the rod on the scale while the other is carried, so each end can be weighed and matched independently.

• Holds each end of a connecting rod on the scale separately.
• Allows the big end and small end to be weighed and matched independently.
