Installation Instructions for 12,000 lb. Square Tube Jack
General Installation Notes:
- Ensure installation follows the instructions without any alterations or modifications to the product.
- Never position any part of the body under the product or the load being supported.
- Fully retract and/or rotate the jack before towing.
- Ensure the drop leg pin is fully inserted before using the jack.
- Block wheels to prevent rolling when operating the jack or coupling the trailer.
- Do not exceed the maximum rated capacity. Refer to the markings or decals on the product for rated capacity.
- Avoid excessive side forces, as they may cause jack failure.
- Replace any bent, broken, or worn parts before use.
- Use only on flat surfaces. For tandem applications, ensure jacks raise and lower together to share the load equally.
- All welding must be performed by an AWS-certified welder.
Tools Required:

Step-by-Step Instructions:
Direct Mount to Load-Bearing Member:
- All welding must be performed by an AWS-certified welder.
- Place three 2-inch-long 1/4” fillet welds on both sides of the jack along the contacting surface. Welds should be spaced as far apart as possible for maximum strength.
- For tandem applications, align the jacks carefully so they raise and lower together and share the load equally.
Weld-On Pivot Tube Mounting:
- Position the non-beveled side of the pivot tube against the tongue.
- Weld all around the tube using a 1/4” fillet weld.
- Align one set of pivot mount holes vertically, mate the jack to the pivot tube, and secure with the supplied pin.
