What Is a Frame Jack?

Published in Trailer Jacks 2 mins read

A frame jack, particularly as described by CURT, is a type of trailer jack designed specifically for A-frame trailers. These essential components are used to lift and support the front of a trailer when it's not connected to a towing vehicle, making it easier to level, connect, or disconnect.

Key Features of A-Frame Trailer Jacks

Based on the provided reference about CURT A-frame trailer jacks, these jacks have distinct characteristics:

  • Specific Design: They are engineered to fit the triangular (A-frame) front structure of compatible trailers.
  • Installation Methods: These jacks offer flexibility in how they are attached to the trailer frame.
    • Bolted On: Allows for easier replacement or removal.
    • Welded On: Provides a more permanent and potentially stronger connection.
  • Operating Mechanisms: They come with different handle and crank styles for extending and retracting the jack:
    • Top-Wind: The crank handle is located at the top of the jack.
    • Side-Wind: The crank handle is located on the side of the jack.
    • Handle types include claw or straight designs.
  • Weight Capacity: A-frame trailer jacks are built to handle significant loads, supporting the trailer's tongue weight. Options are available in capacities up to 5,000 pounds.

Practical Uses

A frame jack is crucial for:

  • Coupling and Uncoupling: Raising or lowering the trailer coupler onto or off the hitch ball of a tow vehicle.
  • Leveling: Adjusting the height of the trailer tongue to achieve a level trailer when parked.
  • Support: Providing stable support for the front of the trailer when it is detached.

Understanding the type, installation, and capacity is important when selecting the right frame jack for a specific A-frame trailer application.
