🔧 Round Tube or Square Tube — what’s the difference in a parking jack?
The tube design may look like a simple structural difference, but it will influence how a parking jack performs in different applications.
🔹 Round Tube Parking Jacks
The round-tube structure generally allows for a lighter overall design, making it a practical choice where reducing weight and easier handling are priorities.
🔹 Square Tube Parking Jacks
With both the inner and outer tubes designed in a square profile, the structure helps limit unwanted rotation during lifting and lowering, providing more stable vertical movement and support.
Which one should you choose?
It depends on the application. Round-tube designs are lightweight and easy to handle, while square-tube structures provide greater lifting stability and controlled vertical movement.
DNL offers parking jacks in various tube structures, load capacities, and configurations for different trailer and equipment applications.
