Piper Backup Wrench

When you could use an extra hand…


Developed for the Craftsman
The Piper Backup Wrench allows the craftsman a safe and effective way to get the job done. With The Piper Backup Wrench and one wrench, the craftsman can balance and position himself better. It also means easier access to nuts in tight spaces. When your craftsmen are using The Piper Backup Wrench tool, they can work with the assurance that it will stay where it is needed. The Piper Backup Wrench holds on to the nut securely even on the underside of flanges. The safety chain prevents The Piper Backup Wrench from falling out of reach when being installed and removed.

It’s all in the design
The unique spring loaded ball plunger mechanism holds The Piper Backup Wrench securely in place whether in use on the top of a flange or underneath. And the simplicity of the overall design allows us to produce specialty sizes when standard sizes don’t meet your needs.

The Piper Backup Wrench is cast from 8630 steel alloyed with nickel, chrome, and molybdenum. After machining, the tools are carburized, quenched, and tempered to 34-36RC. The finished strength levels are: 150,000 lbs per square inch Tensile – 125,000 lbs per square inch Yield

The Piper Backup Wrench tools can be purchase individually or in standard sets. A 6-tool set will accommodate ½” to 20” class 150#, and ½” to 12” class 300# flanges.
