Full details

The Laser 5057 Impact Extension Bar is designed for mechanics and automotive professionals who need to efficiently tighten or loosen fasteners in hard-to-reach areas. Its key benefit is the integrated aluminium spinner sleeve, which significantly speeds up the process by allowing rapid rotation. A minor caveat is its specialized nature, intended primarily for impact wrench use.

FAQs

What is the main advantage of the spinner sleeve?

The spinner sleeve allows for rapid rotation of the extension bar and socket by hand, significantly speeding up the process of tightening or loosening fasteners once they are initially broken free or fully seated.

Can I use this with a manual ratchet?

While technically possible for very light tasks, it is not recommended. The spinner sleeve is designed for use with impact wrenches, and attempting to apply high torque manually through the sleeve can lead to damage or inefficient operation.

What material is the extension bar made from?

It is manufactured from chrome molybdenum steel, a material known for its strength and durability, making it suitable for high-torque applications.

How does the black phosphate finish benefit the product?

The black phosphate finish provides excellent corrosion resistance and helps protect the tool from scratches and wear, contributing to its longevity and maintaining a professional appearance.

What is the drive size of this extension bar?

The drive size is 3/4""D, meaning it is designed to connect with 3/4 inch drive impact wrenches and sockets.

How long is the Laser 5057 Impact Extension Bar?

The length of the extension bar is 250mm.

Troubleshooting

Spinner sleeve is stiff or difficult to turn.

Ensure there is no debris trapped between the spinner sleeve and the main bar. Apply a small amount of light lubricant if necessary, and work the sleeve back and forth.

Extension bar does not fit impact wrench securely.

Verify that both the impact wrench and the socket being used have a 3/4""D drive. Ensure the drive pin mechanism on the impact wrench is functioning correctly.

Excessive vibration during use.

Check that the socket is properly seated on the extension bar and the extension bar is securely attached to the impact wrench. Ensure the fastener being worked on is not cross-threaded.

Pros and Cons

Pros

  • Significantly reduces task time due to the spinner sleeve.
  • Durable construction for heavy-duty impact wrench use.
  • Enhanced grip and handling with the spinner sleeve.
  • Corrosion-resistant black phosphate finish for longevity.
  • Provides necessary reach for complex applications.

Cons

  • Primarily designed for impact wrenches, may be overkill for manual use.
  • The 3/4""D drive may not be compatible with all standard socket sets.
  • Spinner sleeve adds a slight bulk compared to a standard extension bar.

Setup, Compatibility & Care

Setup: To use the Laser 5057 Impact Extension Bar, simply attach your desired 3/4""D impact socket to one end and connect the other end to your 3/4""D impact wrench. Ensure a secure fitment for both connections.

Compatibility: This extension bar is specifically designed for use with 3/4""D impact wrenches and sockets. It is not recommended for use with standard manual ratchets unless the fastener is already very loose, as the spinner sleeve mechanism is not intended for high torque manual operation.

Care: After use, clean the extension bar with a dry or slightly damp cloth to remove dirt and grease. Avoid abrasive cleaners. Store in a dry place to prevent corrosion, although the black phosphate finish offers good protection. Periodically check for any signs of wear or damage.
