Built for fastening applications where high power and compact access are both important, the Chicago Pneumatic CP9427 Ultra Compact Ratchet Wrench combines a 3/8" square output drive, 270 RPM free speed, and 25.8 ft-lbs maximum reverse torque. Its extremely compact 5.04" overall length provides improved access in hard-to-reach areas while the 3/8" output drive accommodates compatible sockets.
The CP9427 shares the same high-power, ultra-compact configuration as the CP9426 and adds a 3/8" output drive with socket release button. The catalog specifies a 5.2–7 ft-lbs reverse working torque range, 1.08 lb net weight, and 11 CFM air consumption at load, making this ratchet suitable for compact maintenance and fastening applications where access is limited.
