Overview
This HARFINGTON wrench covers two large fastener sizes, 1 1/8 inch and 1 1/4 inch, on a single 236mm bar. At 0.21 kilograms it is built for turning bigger bolts and nuts in machinery, plumbing or structural work rather than fine adjustment.
Two open-end sizes on one wrench body cut down on the tools needed for a job that moves between 1 1/8 and 1 1/4 inch hardware. A capacity spec of 1.13 inches lines up with the larger jaw opening, and the 236mm length gives real leverage for stubborn large-diameter fasteners without reaching for a separate breaker bar.
- Dual size: 1 1/8 in and 1 1/4 in
- Overall length 236mm
- Item weight 0.21 kg
- Jaw capacity 1.13 inches
Who it's for
Fits mechanics, riggers and maintenance crews working with large SAE fasteners in this size range. Not useful if the hardware on hand runs metric or smaller than an inch across the flats.
Pros and cons
- Two common large sizes on one wrench
- 236mm length adds leverage
- Sized for 1 1/8 and 1 1/4 inch fasteners
- Covers only one size range, nothing smaller
- Bulkier to carry than a standard-size wrench
Performance notes
The 236mm length puts meaningful leverage behind the jaws, useful for cracking loose fasteners that have corroded or been over-torqued. The 0.21 kilogram weight reflects the thicker cross-section needed to resist twisting under that kind of load.
