Gison GP-857: The Ultimate Long-Reach Heavy Duty Air Ratchet
The Gison GP-857 1/2" Heavy Duty Air Ratchet is the definitive choice for technicians dealing with high-torque fasteners in deep, inaccessible areas. Measuring a substantial 360mm in length, this tool provides the extended reach and physical leverage required for heavy transport, agricultural machinery, and industrial plant maintenance.
Engineered for Extreme Torque & Access
While standard ratchets struggle with stubborn bolts, the GP-857 is built for power. It delivers an impressive 90 ft-lb (122 Nm) of working torque, nearly 50% more than standard 1/2" air ratchets.
- Extra Long Reach: The 360mm chassis allows operators to reach deep into engine bays or machine housings that are otherwise inaccessible to impact wrenches.
- Maximum Leverage: The extended body allows the technician to apply manual "break-away" force safely before engaging the pneumatic motor.
- Heavy-Duty Head Design: Reinforced 1/2" drive head designed to withstand the stress of 90 ft-lb torque without slipping or stripping.
- High Bolt Capacity: Specifically rated for fasteners between 8mm and 13mm, making it ideal for heavy-duty chassis and engine work.
