Description:
The shank has an offset bend to put the center of the "T" handle in line with the center of the socket. The ratchet action is reversible by turning the spring-loaded beveled-end click a half turn. The ratchet wheel has a square center opening; sockets for the wrench have a shank with larger and smaller circular bearing surfaces, an intermediate square for the ratchet head, and a hole or notch for a securing clip or wire. The sockets can be positioned to face toward or away from the handle.

Marketed as the TIGER CYLINDER TOOTH WRENCH.
