When you could use an extra hand

Developed for the Craftsman
The Backup Wrench allows the craftsman a safe and effective way to get the job done. With The 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 Backup Wrench tool, they can work with the assurance that it will stay where it is needed. The Backup Wrench holds on to the nut securely even on the underside of flanges. The safety chain prevents The 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 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.

Sold individually or in sets
The 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
