Jack Boss 5 Ton Screw Jack — 10,000 lb Professional Support, Red, 9.5–13.375 in Height, Self-Locking

This compact but powerful screw jack delivers a precise, secure support solution when you need a stable temporary stand for cars, beams, bridges, or house framing. Built from high-quality steel, finished with lead-free paint, and fitted with a corrugated swivel saddle and bell-shaped base, it offers controlled, self-locking elevation from 9.5 inches to 13.375 inches. The unit’s compact footprint and 360° swivel head make it easy to position under awkward loads while its carry handle simplifies transport and storage.

How much load can this screw jack hold and what are its dimensions?

The Jack Boss screw jack is rated for 5 tons (10,000 pounds) of vertical support when used on stable, level surfaces. Its working height ranges from a low 9-1/2 inches to a maximum of 13-3/8 inches, making it suitable for short lifts and support duties rather than long-stroke jacking.

• Capacity: 5 Ton / 10,000 lbs
• Item size: 5.12 x 4.53 x 9.45 inches (compact footprint)
• Working height: 9.5" min to 13.375" max
• Base size: 4.5" x 4.5" for stable contact

What safety and stability features are included?

Safety is addressed with a self-locking screw mechanism that holds the selected height under load, reducing unintentional descent. The bell-shaped, corrugated cast base increases surface contact and resists slipping while a textured, 360° swivel saddle helps align the load without shifting the jack position.

• Self-locking design prevents sudden lowering
• Corrugated swivel saddle promotes better grip on load points
• Bell-shaped cast base adds anti-tip stability on level surfaces
• Lead-free paint finish protects steel from rust and staining

How does this jack perform on-site and how do I handle it?

The jack’s compact weight (about 9.26 lbs) and integrated steel carry handle make it easy to move between job locations or store in a vehicle. The corrugated swivel head and 360° rotation let you fine-tune support alignment without repositioning the base, saving time during installations or temporary shoring tasks.

• Net weight: 9.26 lbs — portable but rugged
• Handle socket: 9/16" diameter for standard turning bars
• Swivel head rotates full circle for quick alignment
• Suitable for upright or inverted use depending on task needs

What warranty and maintenance should I expect?

Jack Boss backs this screw jack with a limited 1-year manufacturer warranty covering defects in materials and workmanship. Routine maintenance is minimal: keep the screw threads clean, inspect for deformation before each use, and touch up the painted finish if chips occur to limit corrosion.

• Limited 1-year manufacturer warranty included
• Recommended: keep threads lubricated and clean
• Inspect saddle and base for wear before each operation
• Store in a dry place to preserve the lead-free finish

Who is this for? The Jack Boss 5 Ton Screw Jack is built for contractors, bridge crews, carpenters, and serious DIYers who need a compact, reliable support for short-lift stabilization tasks. If you require a portable, tough support that balances capacity with precise height control for construction, automotive support, or temporary shoring, this jack offers a practical, on-site solution. It is not intended for use as a primary lifting device for long-term loads without additional engineered supports; always follow local safety codes and load-bearing guidelines when deploying jacks in structural applications.
