Raised Panel Combination Wrench – Ratchet Type (No. 377)
The No. 377 combines a standard open-end jaw with a ratcheting ring end, allowing continuous fastening without removing the tool from the fastener. The raised panel body enhances structural strength while maintaining balanced weight distribution. The ratchet mechanism is designed for smooth engagement and controlled torque transmission, making it ideal for repetitive assembly line operations and confined workspaces.
