US PRO Tools Impact Extension Bar Set - 9pc

These extension bars are compatible with impact tools that use 1/4", 3/8", and 1/2" drives.

They are made from chromium-vanadium steel.

The black oxide finish helps resist abrasion, oxidation, and corrosion.

They should be stored in the provided molded tray to keep them organized and protected.

While the extension bars can physically connect to hand tools, it's not recommended as they are designed for impact tools.

Discontinue use immediately and replace the damaged extension bar to prevent any potential safety hazards.

The set includes extension bars in the following sizes: 1/4" drive (50mm, 100mm, 150mm), 3/8" drive (45mm, 75mm, 150mm), and 1/2" drive (50mm, 125mm, 250mm).

Please refer to the product packaging or retailer for warranty information.

Ensure the correct size socket is being used and that the fastener isn't severely damaged. If stuck, try applying penetrating oil and using a breaker bar to loosen before using the impact tool again.

Check if the retaining ball on your impact tool is functional. Make sure the extension bar is fully seated in the drive.

This is normal, especially under heavy use. Replace worn extension bars to maintain safety and performance. Inspect bars before each use and replace if necessary.
