RPM RPM80412 Pinion Case Black

RPM's RPM80412 Pinion Case keeps your pinion gears protected and organized. Even a single small nick on a pinion can eventually destroy a plastic spur gear — this case solves that by holding each pinion on its own dedicated post with a snap-shut lid, eliminating the need for set-screws to secure pinions in place. Includes a peel-off decal sheet with two pinion-to-spur gear ratio charts (48-pitch and 64-pitch) sized for the recessed area on the bottom of the case, plus numbered squares from 14 to 31 teeth for labeling each post. Ten blank squares are included for custom numbering. Available in black and translucent blue.
