## Abstract

A wrench extension tool for application to a dual open end wrench to increase leverage applied to the wrench and providing multiple position attachments to the end of the open end wrench opposite the end applied to an object removed or applied upon a threaded bolt, stud or shaft, having a variety of attachment positions to the wrench as selected for optimizing application to the open end wrench by a user.

## Claims

### Claim 1

A wrench extension tool for an enhanced application of force and torsion upon a dual open end wrench, said tool comprising:
a body, a first tool end and a second tool end, each said tool end comprising a tool channel, a right side panel, a left side panel, a front panel and rear panel an upper edge of the right side panel, left side panel, front panel and rear panel forming an upper surface with an upper surface tool channel opening, a lower edge of the right side panel, left side panel, front panel and rear panel forming a lower surface with a lower tool channel opening and the tool channel defined by inner surfaces of the right side panel, left side panel, front panel and rear panel;
a first pin attached to said upper surface across said upper tool channel opening of each tool end, wherein said first pin is attached proximate to said respective front panel; and
a second pin attached across said lower tool channel opening of each tool end, wherein said second pin is attached to said lower surface closer to the respective rear panel than the respective first pin; and
wherein a majority of each of said first and second pins is positioned external to the tool channel;
wherein said first tool end and said second tool end are rotationally offset at 90 degrees laterally from one another about a longitudinal axis of said body of said extension tool, and
each said tool channel opening is dimensionally proportional to accept a corresponding open end wrench size, in metric or standard sizes, with said first tool end of a different size than said second tool end, each tool end being adapted to a size of each end of said dual open end wrench to which said extension tool is designated to mate with and fit.

### Claim 2 (depends on 1)

The extension tool of claim 1, further comprising each said front panel and said first and second pin having a rounded profile, each said front panel and said first and second pin combination and orientation providing for at least four selections of positional engagement between said tool channel and said chosen gripped end of said dual open end wrench as chosen by said user of said extension tool.

### Claim 3 (depends on 1)

The extension tool of claim 1, wherein,
a circumference of a cross-section of each said tool end is greater than a cross-sectional circumference of said body of said extension tool connecting said first and second ends, providing an enhanced hand grip of said extension tool.
