Omega Technologies RR2E40S-SP Double-Ended Short-Handle Roller Ratchet®, 1/4” Square Drive with thru-hole for hex keys feature one end for clockwise rotation, the other for counter-clockwise rotation. Omega Technologies Double-Ended Hi-Lok® Roller Ratchet® eliminates the need for a reversible spindle which reduces the occurrence of foreign object debris (FOD) and increases efficiency. Omega Technologies Roller Ratchets® were designed as a response for the need of small ratchet wrenches that could be used in tight areas where the swing of the handle was limited by obstructions, and to have a ratchet or tool that would work with very little handle movement. Roller Ratchets® satisfies both of those requirements.
