Roller Ratchets

Hi-Lok Roller Ratchets were developed in response to the need in the aviation industry for very small ratchet wrenches that could be used in extremely tight spaces on aircraft 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.

With particular emphasis on strength, durability, and quality, we maintain the functionality and cost-effectiveness of the entire line of tools.The Roller Ratchet 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 Roller Ratchet tool compatible with Hi-Lok, Hi-Lite, and Eddie Bolt systems.
