Reversible 1/4” Square Drive Short Handle Roller Ratchet Description
The smallest 1/4” square drive Roller Ratchet®. This Roller Ratchet® accepts all standard 1/4” square drive sockets and has a 1/4” square drive with thru-hole for hex keys. Furnished with reversible spindle.
Roller Ratchets® were developed by Omega Technologies in response to the need for very small ratchet wrenches that could be used in extremely tight areas 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.
