Hi-Lok® Standard Single Roller Ratchets® from MRO Tools. The standard single Roller Ratchet® from MRO Tools provides the same application of a hand ratchet, yet its size greatly increases its functionality by allowing it to be used in tighter areas.The incorporation of a special ‘toothless’ clutch eliminates all lost motion, allowing even the slightest movement to engage the tool. The modular platform allows for an almost limitless configuration. A through-hole also makes the tool compatible with Hi-Lok®, Hi-Lite®, and Eddie Bolt® systems.Roller Ratchets® is a registered trademark of Omega Technologies, Inc.
