What mounting and swivel features does this jack include?

This model is a pipe-mount design meant to be welded onto a trailer’s frame using the supplied raw steel pipe bracket. The swivel mechanism uses a pull-pin system so the jack can pivot up and lock into the travel position when towing.

• Weld-on pipe bracket with 9/16" hole ready for welding
• Pull-pin swivel lets the jack swing up and clear the ground for travel
• Welded foot plate provides stable contact on uneven ground

How easy is it to operate and resist corrosion?

Operation is manual via a side-wind handle that integrates an ergonomic grip for raising and lowering the tongue. The jack is finished in durable black powder coat with zinc-plated components to help slow rust and wear from water, road salt, and debris.

• Side-wind handle for convenient vertical adjustment
• Integrated grip on handle for easier turning and control
• Black powder coat and zinc plating for extended exterior life

What are the size and travel dimensions I should expect?

The 28321 delivers 10 inches of vertical travel to accommodate common hitch heights. Typical retracted and extended measurements provide the range needed to couple and level many trailer types.

• 10" vertical travel from lowest to highest position
• Approximately 17-1/2" retracted and 28-1/2" extended overall handle heights
• Compact weld-on pipe mount keeps jack secure and out of the way when stored
