Roller Ratchets® from Omega Technologies were developed in response to the need for very small ratchet wrenches that could be used in extremely tight spaces where handle ‘swing’ was limited by obstructions, and the need to have a ratchet that would engage with very little handle movement.

The Roller Ratchet® satisfies both of these requirements, and this modular tool is now widely used in the aerospace community worldwide. Roller Ratchets® is a registered trademark of Omega Technologies, Inc.
